Usage
Ensure the PocketScope handle is switched off and disconnected from any instrument head before replacing the cap.
Remove the existing bottom cap (if present) by unscrewing it from the end of the PocketScope AA handle.
Insert or check AA batteries in the handle tube, orienting them according to the polarity markings specified by the handle manufacturer.
Align the new bottom cap with the handle tube and screw it on until it is snug; do not overtighten.
After fitting, switch on the PocketScope instrument to confirm reliable power and illumination.
Inspect the cap periodically for signs of wear, cracking or damaged contacts and replace if necessary as part of routine maintenance.
Contraindications
Not suitable for use with non-compatible handles or diagnostic instruments that are not part of the Welch Allyn PocketScope AA handle family.
Should not be modified, drilled or altered, as this may compromise electrical safety or instrument performance.
Not intended for use with rechargeable handle systems that require a different bottom cap or charging interface, unless explicitly specified as compatible.
Adverse Effects
If incorrectly fitted or cross-threaded, may result in poor electrical contact, intermittent power or failure of the PocketScope instrument.
Use of damaged or cracked caps could expose internal components or batteries, posing a minor risk of battery leakage or loss of power.
Overtightening may damage threads on the handle or cap, requiring further repair or replacement.
Storage Conditions
Store as a spare part in a clean, dry environment at room temperature.
Protect from excessive heat, direct sunlight and moisture to avoid plastic deformation or corrosion of internal contacts.
Keep away from loose metal objects that might scratch or deform the contact surfaces.
