Charging the Speaker Microphone
The BTH-500 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 up to 40 hours 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 off using Volume/Power Knob.
2. Plug the charge cable into any powered USB outlet,
such as an AC wall charger, and then into the charge jack
on the bottom of the speaker microphone.
3. Once the charging process has begun, the LED indicator
on the speaker microphone will show a constant red light.
4. Typical charge time is approximately five hours. Actual charge time will vary depending on
several factors including the battery's charge state, condition, and age.
5. When the battery is fully charged the LED indicator on the speaker microphone will turn off.
6. 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 off when charging.

Pairing with a PRYMEBLU Radio Adapter and 2-way Radio
When pairing the PRYMEBLU Speaker Microphone with a PRYMEBLU Radio Adapter, make sure that the speaker
microphone, adapter, and the two-way radio the adapter is connected to are all powered off to start.
If your PRYMEBLU Radio Adapter gets power directly from the two-way radio it is attached to:
•
Hold down the Talk button on the PRYMEBLU Radio Adapter while turning the two-way radio ON.
If your PRYMEBLU Radio Adapter has its own charger/internal battery pack:
•
Turn the power switch on the PRYMEBLU Radio Adapter to the ON position while holding down the
multifunction Talk button on the PRYMEBLU Radio Adapter.
•
Continue to hold the Talk button on the adapter down for approximately three seconds. Release the Talk
button when the status LED on the PRYMEBLU Radio Adapter begins to flash two times per second. The
PRYMEBLU Radio Adapter is now in audio accessory pairing mode.
•
Hold down the PTTButton on the PRYMEBLU Speaker Microphone while turning the device on using the
Power/Volume Knob.. Continue to hold the button down for approximately 3 seconds, until you see the LED
on the speaker microphone begin to quickly flash RED-BLUE-RED-BLUE in sequence. The PRYMEBLU Speaker
Microphone is now in pairing mode.
Reconnecting a Previously Speaker Microphone and Radio Adapter
Once the PRYMEBLU Speaker Microphone and Radio Adapter have been successfully paired together, both
devices will remember that connection. The adapter and speaker mic will attempt to reestablish their link
whenever the radio/adapter and microphone are both powered on and in within range of each other.
Re-establishing this connection can take 10-60 seconds.
