Charging the Speaker Microphone
The BTH-SPM100-ZD speaker microphone has an internal Lithium Ion rechargeable battery pack which
must be charged prior to operation, and must be recharged regularly. A fully charged battery will
provide approximately 5 hours (or more) of continuous operation before needing to be recharged.
However, operating time can vary depending on usage and the condition of the battery pack.
Recharge the battery regularly.
To charge the speaker microphone
1. Ensure the device is turned o using the multifunction button.
2. Plug the charge cable into any powered USB outlet, such as the included AC wall charger, and then
into the charge jack on the bottom of the speaker microphone. You will need to remove the protective
rubber cover that is inserted into the charge jack. (To prevent dust and moisture from damaging your
speaker microphone, always ensure this cover is in place when you are not charging.)
3. Once the charging process has begun, the LED indicator on the bottom of the speaker microphone
will show a constant red light.
4. Typical charge time is approximately three hours. Actual charge time will vary depending on several
factors including the battery's charge state, condition, and age.
5. Disconnect the charger from the adapter when charging is completed.
Charging Cautions:
- Do not use a wall charger or charge cable that appears to be damaged. (Example: frayed wires,
melted plastic, etc.) Contact PRYME to get a new manufacturer-approved replacement charger.
- Do not tamper with or modify the speaker microphone or charger.
- Always turn the speaker microphone o when charging.
