It is good practice to remove the battery from the charger after it is
fully charged. Regularly leaving a fully charged battery in the charger for
an extended period (such as longer than overnight or over a weekend),
may shorten battery life. In addition, the ambient temperature should be
+50° to +95° F (+10° to +35° C) when recharging a battery.
NOTE: It is recommended that one of the rapid chargers be used when-
ever possible (especially the new technology DT/Dt chargers listed on the
preceding page). Using those chargers normally results in longer battery
life, longer operating time, and faster recharging.
Speaking Into Microphone
For best results, hold the speaker grille about l-2 inches away from
your mouth and speak slowly and distinctly at a normal conversational
level. Do not shout since it distorts your voice and does not increase
range. Make sure the push-to-talk switch is pressed before you begin to
speak and released as soon as the message is complete.
Operation At Extended Range
When approaching the limits of radio range, the other party may not
always hear your transmissions and there may be an increase in back-
ground noise when messages are received. Communication may be
improved by moving to higher ground or away from shielding structures
such as tall buildings and hills.
FCC Licensing
To operate this transceiver on the air, it is usually necessary to file
the proper license application. Your system operator will provide you
with the necessary information regarding licensing requirements.
