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.

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
Do not cut the R607 resistor if
connecting an HESB to the HHEU
for the Loud Ringing Bell–even if a
headset is also installed on the
HHEU.

For the V.4 HHEU1 and the HHEU2: if
only the headset is connected to the
