VOLTAGE LO - The input voltage to the mobile is too low. 

Write Fail - The radio is unable to write to the EEPROM. 

As noted several times in this manual, programming determines the availability and 
specific operation of many features. This usually refers to the programming performed by 
your system operator when the radio was set up, not to any programming that a user can 
perform. If a feature is controlled by a front panel option switch and that switch is not 
available, it is probably not available.

An exception is Keypad Programming which can allow the user to reprogram several 
conventional channel parameters. Refer to Section 5.16 for more information.

For best results, hold the microphone about 1-2 inches from your mouth and speak at a 
normal conversational level. Do not shout since it distorts your voice and does not increase 
range. Make sure that the PTT (push-to-talk) switch is pressed before you begin to speak 
and released as soon as the message is complete.

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 radio. Communication may be improved by moving to 
higher ground or away from shielding objects such as tall buildings or hills.

In the standby mode (power on, not transmitting), radio power consumption is relatively 
low. Therefore, you can probably leave the radio 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 radio 
should be turned off when not in use.
