MISCELLANEOUS
ground noise when messages are received. You may still be out of range even though you can hear a message. The reason for this is that the signal you are receiving is usually transmitted at a higher power level than the one transmitted by your transceiver. Communication may be improved by moving to higher ground or away from shielding objects such as tall buildings or hills.
Preventing Battery Discharge
In the standby mode (power on, not transmitting), transceiver power consumption is relatively low. Therefore, you can probably leave the transceiver on for one or two days without operating the vehicle and the battery should not become seriously discharged. However, if the outdoor temperature is low enough to significantly decrease battery capacity, the transceiver should be turned off when not in use.
Since power consumption is significantly higher when transmitting, it is good practice to have the vehicle running while transmitting. This ensures that optimum power is being delivered to the transceiver and that the battery does not become discharged.
Licensing
A government license is usually required to operate this transceiver on the air. Your system operator will normally handle the licensing requirements.
Transceiver Service
If your transceiver is not operating properly,
“PROG ERR” may be displayed. To attempt to clear this condition, turn power off and then on again to reset the control logic. Another indication that could be displayed is “NO POWER”. This indicates that transmitter temperature or supply voltage may be excessive. Release the PTT switch and allow the transceiver to cool, and make sure that the vehicle battery voltage is within the normal range.
