amplifier on the MTOU, and the
voice path will be one way.
If
600 ohms is selected, an external
PA amplifier or talk-back amplifier
is required and the internal voice
path will be two way.
05.02 To equip either of the two
relay service functions; obtain the op-
tional relay from your Toshiba supplier
and install it in the proper location on
the !V!TOU, per Figure 5.

05.03 External page impedance is
selected with the SW 2 switch located
adjacent to the relay sockets on the
!V!TOU PCB (Figure 6). Decide if 8- or
600-ohm impedance is required, then
make the selection by positioning the
SW2 switch to
n3n
or
11
600", whichever
is required. Figure 6 shows the switch
in the 8-ohm position.

NOTE:
For proper static electri-
city protection, install the
PCBs in the Following se-
quence.
• MTOU (Tone Unit)-one per system.
• CRDU (Repertory Dial Unit)--one
per system, to be installed on the
MCCU PCB when the Automatic
Dialing-Station option is required.
• MCCU (Central Control Unit)--one
per system.
• MSTU (Station Interface Unit)-
install one for each group of eight
stations. System maximum is two
(16 stations).
• MCOU (Central Office Unit)-in-
stall one for each group of three
CO/PBX lines. System maximum is
two (six lines). Two types of
MCOU are available.
