GLOSSARY
1 MHz step
A function that steps the transceiver up or down in
frequency by exactly 1 megahertz and increments or
decrements the MHz digit by 1. The function works in a
circular fashion. If a 1 megahertz step places the new
frequency outside the transceiver band limit, the
transceiver sets the MHz digit such that the new
frequency is inside the opposite band limit.
APO (Automatic Power Off)
A function that automatically turns OFF the transceiver
after some period of inactivity. The purpose is to prevent
a forgetful operator from accidentally discharging the
transceiver’s battery supply.
Auto Page Cancel
A function that automatically switches OFF the Page
function after Page codes have been transmitted. The
purpose is to avoid sending Page codes at the start of
every transmission.
Automatic Transmit Offset
This function is for repeater users. It automatically
selects the correct transmit frequency offset (both
direction and amount) according to established band
plans.
Autopatch
A service available widely in the U.S.A. and Canada that
allows portable or mobile stations to access the public
switched network by connecting through a local repeater.
Telephone numbers are sent via DTMF signals by using
the keypad. Only non-commercial communication is
authorized.
Battery Saver
An energy-saving function that reduces power
consumption after 5 seconds of inactivity. The function
makes possible longer times between battery charges.
BNC
A threadless connector universally used at VHF and
lower UHF frequencies. The connection is secured by a
quarter-twist of the male connector.
Beep Tone
A selectable function that generates a tone each time a
key is pressed to provide audible confirmation that the
key was actually pressed, or to provide an error tone to
indicate an error condition exists.
Busy Frequency Lock-out
A function that automatically prevents transmission on a
frequency that is busy.
