Music-on-hold/Background Music Volume Control (External Options)
Each of the common control units (except RCTUBB, RCTUD and RCTUF) has a trim
potentiometer (VR1) to adjust the volume of the MOH/BGM source connected to the Music-on-
hold (MOH)/Background Music (BGM) RCA jack interface, which is also on the common control
unit. The volume control potentiometer and the MOH/BGM interface are on the RCTUA,
RCTUBA3, RCTUA4, RCTUC, RCTUE3 and RCTUE4 PCBs.
The VR1 potentiometer does not control the volume of alternate BGM sources connected to either
the RSTU2, RDSU, PSTU, PEKU, PESU, or other BGM source interfaces.
➤
To install the MOH/BGM source to common control unit
➤
Adjust the VR1 potentiometer to the desired volume level while listening to MOH or BGM
(see Chapter 12 – Peripheral Installation).
RRCS
The DTMF receiver subassembly (RRCS) translates DTMF signals to data signals and attaches to
common control units with 4, 8, or 12 receiver circuits.
RRCS (4, 8, or 12) Installation onto RCTUA
➤
Mate RRCS connectors J1, J2, J3, and J4 (
) with RCTUA connectors P2, P3, P4,
P5. Apply firm, even pressure to the RRCS to ensure proper mating of the connectors.
RRCS Installation onto RCTUBA, RCTUC/D, and RCTUE/F
RCTUBA provides up to 12 DTMF receiver circuits because an RRCS PCB can be installed on
RCTUBA only and not on RCTUBB.
