Setup, Compatibility & Care
The device is ready for use straight out of the box. To replace the battery, locate the small screw or panel on the back of the device; it uses an LR1130 battery, which is fully compatible with the widely available GP 189 standard. Keep the device away from extreme temperatures and moisture to protect the internal circuitry. To clean the exterior and keys, use a dry, soft microfiber cloth. Avoid using harsh chemical solvents, as these may damage the plastic casing or the display cover.
