these steps:
1. Loosen the four captive screws on the
telephone base, and remove the base.
2. Use a screwdriver or other suitable
tool to remove the plastic tab on the
back of the base. (The HHEU modular
connector for the headset is accessed
through this opening.)
3. If installing a V.3 HHEU1, set the
SW601 switch on the HHEU to
headset for the headset or loud bell
application.
V.4 HHEU1 and HHEU2 do not have
this switch, because they are
automatically set for the headset/loud
bell application.
4. Connect the HESC-65A cable to P601 of the
HHEU (both HHEU1A versions and the
HHEU2 have P601) if the Loud Ringing Bell
option is required.
Refer to
HESB installation procedures.
5. For the V.3 HHEU1: If only the headset is
connected to the HHEU, cut both sides of the
R607 resistor, then remove the resistor to
eliminate electrical contact.
Note
...or
For the V.4 HHEU1 and the HHEU2: if only
the headset is connected to the HHEU, cut the
speaker OCA strap.
Note
6. Position the HHEU PCB on the standoffs inside the base, and secure with the two provided
screws.
