PTT button (front panel): Allows telephone style units
to transmit without lifting the handset using the panel
microphone. On console style units it functions the same
as the desk mic PTT.
PTT button (handset): Off-hook it allows telephone
style units to transmit with handset.
Intercom switch: Provides intercom capability between
parallel remotes or the radio. Can be used by depressing

To intercom between the radio and a remote, press and
hold the intercom switch on the termination panel and
speak into the local microphone while keying it.
Parallel operation
Up to 50 MCR /TSR series remote units may be con-
nected in parallel.
As parallel units are installed, the setup procedure need
only be performed on the new remote(s). The existing
remotes do not require readjustment.
Motorola Trunking
Since remote operation with Motorola Trunking has some
unique requirements, more detail follows.
Most of the remotes operating feature are the same as
the radio and therefore only the differences will be
described here.
TRANSMITTING ON A TRUNKED SYSTEM: The
remote's transmit LED will always light steady when PTT,
handset or front panel, is depressed. You therefore must
listen for the high-pitched "di-di-dit" talk permit tone to let
you know it is OK to transmit.
Other tones such as the talk prohibit tone or the busy
tone may be heard depending on system status. Refer
to your radio's operating instructions for explanations of
these tones. These tones will not be heard when trans-
mitting on-hook, they will only be heard when using the
handset.
TRANSMITTING ON A CONVENTIONAL SYSTEM:
The remote's transmit LED will always light steady when
PTT, Handset or front panel, is depressed. You there-
fore must listen for the high-pitched "di-di-dit" talk permit
tone to let you know it is OK to transmit. Do not transmit
if some else is using the channel. These tones will not be
heard when transmitting on-hook, they will only be heard
when using the handset.
CALL ALERT ®: When a Call Alert is received, the
amber call LED will light steady and you will hear the
four tones over the remote's speaker and handset
earpiece. The display will not show "CA". You will
continue to hear the alert tones and the call LED will stay
lit until a PTT or system change is made.
Sending a Call Alert is done much the same as the on
the radio, with some minor deferences. There will be no
call LED activity, you must listen for the single beep to
indicate the call alert has been sent. When the Call Alert
is acknowledged you will hear the four beeps but there
will be no call LED activity on the remote.
TELEPHONE INTERCONNECT OPERATION: Not
supported from the remote.
SCAN LIST: Programming or altering the scan list can
not be done from the remote. It must be done from the
radio.
NUISANCE DELETE SCAN FEATURE: Not supported
from the remotes.
