Before Using this Terminal
• Plug or unplug the connector slowly and
securely avoiding excessive force.
• If you start charging the fully drained battery pack,
this terminal may not be turned on for a while.
• If you make communication while charging,
the inside of this terminal may become hot
and charging may stop. In this case, end the
functions in use and wait until this terminal
becomes cool down, and then try charging again.
• Depending on the usage condition, charging
may stop before the battery level becomes
100%. In this case, remove the battery pack
and attach it again to continue charging.
• Do not remove the battery pack while
charging. If the battery pack is removed,
the power does not correctly turn on or the
battery is not correctly charged. In that case,
remove the battery pack and all cables from
this terminal, and reconnect them.
■ Do not charge the battery pack for a long time
(several days) with this terminal power on.
• If this terminal is left with the power on for long
periods of time during charging, you may not
be able to use this terminal for long duration as
expected, because this terminal receives the
power from the battery pack after charging
completes. In this case, recharge the battery
pack properly. Before recharging the battery
pack, disconnect the AC adapter or DC
adapter from this terminal and reconnect it.

• Continuous communication time is the
approximate usage time when you can
normally send and receive radio waves.
• Continuous stand-by time is approximate
usage time when moving with normal radio
wave reception level.
• Communication time or operating time may be
reduced by half depending on the battery level,
set functions, operating environment such as
ambient temperature, or radio wave reception
level (poor or weak radio wave reception level).
