What to do if my POLMAR DB-10 Radio has no electrical source?
If your POLMAR Radio has no electrical source, the battery may be exhausted. Try replacing or recharging the battery. Alternatively, the battery might be installed incorrectly; remove it and install it again correctly.
What to do if other radios cannot receive TX signals from my POLMAR Radio, or receive them in low volume?
If other radios are not receiving the TX signals from your POLMAR Radio, or the volume is low, ensure the volume knob is set to the highest level. If the problem persists, the microphone may be damaged and should be checked by a local dealer.
Why am I not able to communicate with transceivers of the same group using my POLMAR Radio?
If you are unable to communicate with transceivers in the same group using your POLMAR Radio, confirm that the CTCSS/DCS tone is the same for all transceivers. Also, the distance between the radios may be too far; ensure you are within the operational range.
