VRS Installation

When selecting the location for the VRS, make certain that there is
sufficient clearance for routing the antenna cable to the rear of the
unit.
The VRS750 is installed using the HKN6153A interface cable. The
molded DB-25 end connects to the ASTRO mobile front connector.
The DB-25 end with the plastic housing connects to the VRS (see
Figure 2).

If an external Siren/PA is to be used, the G334AC option must be
ordered which replaces the HKN6153A cable with a HKN6154A cable,
or a separate HKN6154A cable must be ordered. To install, plug the "T"
side of the HKN6154A cable to the Siren/PA. Replace the mounting
screw on the HKN4363B cable with the double length screw. Plug this
side into the "T" cable. Plug the DB-25 end of the HKN6154A into the
VRS (see Figure 3).
