7. Connect the wire plug of the HHEU PCB to the HHEU connector on the PCB in the phone.
8. If an HESB will be connected to the HHEU (for Loud Ringing Bell), locate the EX.SP strap on
the PCB in the telephone and cut the strap.
9. If a headset will be connected to the HHEU, locate and cut the HHEU strap on the PCB in the
phone.
Note
If the HHEU PCB is removed from the phone, the HHEU strap must be replaced for
proper telephone operation.
10. Reinstall the telephone base; secure with the four captive screws.
Notes
●
There are two types of HHEUs: the HHEU1 (which has four versions, V.1~V.4) and the
HHEU2.
●
2000-series digital telephones require either an HHEU2 or a V.3 or V.4 HHEU1 for HESB
operation; earlier HHEU1 versions are only sufficient for headset operation only.
●
Only digital telephones equipped with an HHEU2 can be wall mounted. The HHEU2 is
identical to the V.4 HHEU1, except that the HHEU2 has longer wires to accommodate wall
mounting.
●
A Toshiba HESC-65A cable is required to connect the HHEU in a digital telephone to the
HESB.
