Loosen the four captive screws on the telephone base and remove the base.
Align the P5 connector on the HVSI subassembly with the receptacle on the HVSU
subassembly.
Apply firm, even pressure to the PCBs to ensure that the connectors mate properly (they
should click).
Exercise care when assembling the HVSU to the HVSI to prevent damage to the
connector pins; also, verify that the HVSU is aligned with the silk-screened image
on the HVSI.
Position the HVSU/HVSI subassembly on the standoffs inside the base, and secure with
the two screws provided.
Connect the HVSU/HVSI subassembly wire plug to the P2 connector on the electronic
telephone PCB.
Reinstall the electronic telephone base, and secure it with its four captive screws.
There are two types of HHEU: the HHEU1 (which has four versions, V.1~V.4) and the
HHEU2.
Only electronic 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-65 or HESC-65A cable is required to connect the HHEU in an
electronic telephone to the HESB. Refer to
installation procedures.
All HHEU versions and types, except for V.1 HHEU1, are compatible with the Speaker
Off-hook Call Announce upgrades (HVSU2 and HVSU/HVSI).
