Status Indicators

Shows the current battery voltage
level.
If the voltage level is high, three bars ap-

The displayed battery level shows
the terminal voltage of the battery
cartridge, not how much power is
left.
The battery voltage level varies
depending upon the operation of the
BHT, so the displayed level also may
vary .

SF
shifted.
Alphabet input
Shows a bar when the alphabet in-
ALP
put function is activated.
Connection state in radio commu-
nication

chronized with an access point.
