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 (see Figure 5-9). Refer
to Chapter 6 – Peripheral Installation for HESB & T001B installation procedures.
5. For the V.3 HHEU1: If only the headset is connected to the HHEU, cut both sides of the
R607 resistor (Figure 5-8), then remove the resistor to eliminate electrical contact.
Note
Do not cut the R607 resistor if connecting an HESB & T001B to the HHEU for the
Loud Ringing Bell–even if a headset is also installed on the HHEU.
...or
For the V.4 HHEU1 and the HHEU2: if only the headset is connected to the HHEU, cut
the speaker OCA strap (see Figure 5-8).
Note
Do not cut the speaker OCA strap if connecting an HESB T001B to the HHEU for
the Loud Ringing Bell–even if a headset is also installed on the HHEU.
6. Position the HHEU PCB on the standoffs inside the base (see Figure 5-8), and secure
with the two screws provided.
7. For 2000-series digital telephones, see Figure 5-6 (DKT2010-FH) or Figure 5-7
(DKT2010-FSD, DKT2020-FS, DKT2020-FSD). Connect the wire plug of the HHEU
PCB to the HHEU connector on the printed circuit board (PCB) of the telephone.
8. For 2000-series digital telephones, see Figure 5-6 (DKT2010-FH) or Figure 5-7
(DKT2010-FS, DKT2010-FSD, DKT2020-FS, DKT2020-FSD), and locate the EX.SP
