5.1 User Troubleshooting
When approaching the limits of radio range, the other party may not be able to hear your
transmissions and there may be an increase in background 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.
5.2 5300 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.
