PSION TEKLOGIX 7535 — REPAIR, RENTALS & REFURBISHED UNITS
In-House Repair · Rentals · Refurbished Units · Buyback
The Psion Teklogix 7535 is a discontinued rugged handheld computer that Sterling Mobile repairs in-house at its Phoenix depot, rents for inventory counts and peak periods, sells refurbished with a free 90-day warranty, and buys back when fleets retire it. Psion Teklogix was absorbed into Motorola Solutions in 2012 and then into Zebra in 2014, so there is no manufacturer to send a 7535 to — an independent depot with five in-house technicians is the practical route to keeping one in service.
Psion Teklogix 7535 Repair — Ship In Nationwide or Drop Off in Phoenix
Sterling Mobile repairs the Psion Teklogix 7535 at the component level: scan engine, keypad, display and touchscreen, battery contacts and charging circuit, 802.11 radio, main board, and the housing itself. Pricing is quoted and approved before any work begins, all work is done by our five in-house technicians in South Phoenix — nothing is outsourced — and every repair comes back under a free 90-day warranty with no maintenance contract required.
A handheld ships cheaply, so 7535 repair is a nationwide service: pack the unit using our repair packing list and ship it to the depot. Businesses in Phoenix, Tempe, Chandler, Mesa, Scottsdale and Glendale can drop off and pick up at 5631 S 24th St and skip shipping altogether. If you are sending a fleet, we work them as a batch and return them together.

Not sure what is wrong? Our barcode scanner repair page covers the diagnostic process we use across 20+ brands and hundreds of models, and the Motorola, Symbol and Psion Teklogix repair page explains how these legacy brands relate to each other. Part-number searches — battery, scan engine, cradle or charger numbers such as P30070 — can be sent straight to us with the symptom; we identify the part from the number.
Psion Teklogix 7535 Rentals
Sterling Mobile rents Psion Teklogix 7535 units for short-term and long-term use, which is how fleets bridge a physical inventory count, a seasonal peak, or the weeks a batch of their own units spends on the bench. Rental units are refurbished, tested and configured before they ship, and rentals are available shipped nationwide or collected in Phoenix. Because the 7535 runs the same applications your existing fleet does, a rental slots in without retraining or reconfiguration. Quantities and terms are quoted per request through our equipment rentals page.
Refurbished Psion Teklogix 7535 Units and Buyback
Refurbished hardware typically saves 25–50% against the cost of new, and every refurbished 7535 Sterling Mobile sells has been through the same process: teardown, cleaning, replacement of worn parts, testing to the manufacturer's specifications, and a free 90-day warranty. Because no new 7535s exist, refurbished stock depends on buyback intake — ask for a quote on current units and configurations rather than relying on a listing. Sterling Mobile Complete Care maintenance programs are available on refurbished hardware for up to three years.
| Your situation | Best move | What it involves |
|---|---|---|
| A working fleet with a few failed units | Repair | Quoted before work starts, in-house, 90-day warranty; batch pricing for fleets |
| Need more units on the same software without a migration | Buy refurbished | Refurbished inventory, 25–50% below new |
| Inventory count, peak season, or units away for repair | Rent | Short- and long-term 7535 rentals, shipped or collected |
| Planning to move off Windows CE hardware | Migrate in stages | Keep the 7535s running while Android units phase in — see our end-of-life replacement guide |
| Retired 7535s in a drawer | Sell them to us | We buy surplus equipment, working or not |
Psion Teklogix 7535 Specifications
The 7535 is a pistol-grip or hand-held rugged computer built for warehouse and distribution work. It carries a 1.8-metre drop rating to polished concrete, an IP65 seal against dust and moisture, and an operating range of −10 °C to +50 °C (14 °F to 122 °F). The quarter-VGA display is readable in direct sunlight, the backlit hard-capped keypad is built for gloved use and does not wear through, and integrated Wi-Fi and Bluetooth connect it to existing wireless infrastructure. It runs Windows CE, which is why so many are still in service: the applications written for it in the 2000s still run on it today.

Full figures, including scan engine and radio options by configuration, are in the original Psion Teklogix 7535 G2 specification sheet (PDF). Verify against the configuration label on the unit before ordering batteries, cradles or scan engines — the 7535 and 7535 G2 differ in several parts.
The 7535 is not a Workabout Pro. The two are often confused because both are Psion Teklogix handhelds from the same era. The Workabout Pro family (7525, 7527, 7528) is a separate platform with its own batteries, cradles and parts; we service it too, on its own Workabout Pro 4 page.
What Happened to Psion Teklogix — and Who Supports the 7535 Now
Psion Teklogix stopped existing as an independent company in 2012, when Motorola Solutions acquired it; two years later Motorola Solutions sold its enterprise business, Psion products included, to Zebra Technologies. The 7535 had already been discontinued before the first of those deals, so there has been no manufacturer repair path for it for well over a decade. That is the ownership chain behind every "who bought Psion" question, and it is why independent depots are where Psion hardware gets serviced.
| Period | Owner of the Psion Teklogix line | What it means for a 7535 today |
|---|---|---|
| 2000 – 2012 | Psion Teklogix (Psion PLC, Mississauga, Ontario) | The 7535 and 7535 G2 were designed and built in this period |
| 2012 – 2014 | Motorola Solutions | Psion brand retired; product lines folded into Motorola's enterprise portfolio |
| 2014 – present | Zebra Technologies | Zebra inherited the portfolio but does not service the 7535 |
| Now | Independent repair depots | Sterling Mobile repairs, rents, refurbishes and buys the 7535 and related Psion models |
Besides the 7535, Sterling Mobile services the Psion Teklogix 7035, the 8525 and 8530 vehicle-mount and hand-held units, the Workabout Pro family, and the Omnii XT10 and XT15. The same in-house depot handles the Motorola and Symbol hardware that Psion's lineage eventually merged with, which matters for mixed fleets: one packing slip, one bench, one return.
Arizona note. Handhelds in non-climate-controlled Phoenix-area warehouses along the I-10 and I-17 corridors see summer ambient temperatures that sit at the top of the 7535's +50 °C rating. Batteries age faster in that heat and scan-engine windows scratch faster from dust. If your 7535s work outdoors or in an open dock here, battery replacement and window cleaning are the two jobs that keep them in service longest.
Psion Teklogix 7535 FAQs
What happened to the company Psion?
Psion PLC sold its Psion Teklogix rugged-computer business to Motorola Solutions in 2012. In 2014 Motorola Solutions sold its enterprise business, including the former Psion product lines, to Zebra Technologies. The Psion brand was retired along the way, and Zebra does not service the 7535.
Does Psion Teklogix still exist?
Not as a company. Its products passed to Motorola Solutions in 2012 and to Zebra in 2014. The hardware still exists in large numbers — 7535s, 8525s and Workabout Pros are still running warehouse applications — and independent depots such as Sterling Mobile keep them in service with repair, refurbished units and buyback.
Can a Psion Teklogix 7535 still be repaired?
Yes. Sterling Mobile repairs the 7535 in-house — scan engine, keypad, display, battery and charging, radio, main board and housing — with pricing quoted before work starts and a free 90-day warranty on the repair. Ship it in using the repair packing list or drop it off at the Phoenix depot.
Can I rent Psion Teklogix 7535 units?
Yes. Short- and long-term 7535 rentals are available, refurbished and tested before shipping, for inventory counts, peak periods or to cover units that are away for repair. Quantities and terms are quoted per request; Phoenix-area businesses can collect from the depot.
Is the 7535 the same as the Workabout Pro?
No. The 7535 and the Workabout Pro (7525, 7527, 7528) are different Psion Teklogix platforms with different batteries, cradles and parts. Check the model label on the back of the unit before ordering anything; we service both.
Should I keep repairing 7535s or replace them?
Repair while the application still runs on Windows CE and a replacement would mean rewriting or re-certifying software; replace in stages when the software is ready for Android. Most fleets do both — repairing the working units and buying refurbished to fill gaps, while an Android migration is planned unit by unit. We buy the retired 7535s when that migration completes.
