Alpha Communications VM25WH Series Installation And Use Instructions Manual page 4

NOTE: Each HT2006 handset comes with a loose push
button cap with a 'Key Symbol' on it. If you are using one of
the 5 or 10 push buttons to activate an electric door release,
you may (carefully) 'pop-out' the numbered cap and 'pop-in'
the 'Key Symbol' cap, to make it easier to identify the door
release push button. You do not need to do this to make the
push button activate the electric door release.

* These buttons and cap blanks are used on other systems
and do not apply to this configuration

Turn off the power to the system by disconnecting the
120VAC primary power switch of disconnecting 1 side of the
16VAC transformer from the NH208TVU.
Locate the 5-pin male connector found under the handset
cradle switch, on the handset's p.c. board.
Gently slide the female 5-pin connector on the R2006 p.c. board
onto the 5-pin male connector on the handset's p.c. board, with
the component side of the R2006 p.c. board facing downwards.
Make sure the 5 pins align properly and are not bent or shorting
and the p.c. board cut-out clears the cradle switch mechanism.
Peel the self-stick backing from the round black sounder
component and stick to the handset base. The best location
would be to the left of the (silver) electric buzzer.
Position the wires inside the handset base, so they will not get
'pinched' when the cover is placed over the base.
Re-connect the power to the NH208TVU amplifier.
