1. Description
1.1 The speaker/ampliÞer consists of a 6-watt
integrated circuit ampliÞer and a 2.0 ohm speaker,
enclosed in a rugged, weather -resistant housing.
The housing is designed to be mounted either
inside or outside (Please see the Window
Mounting Bracket Detail, Figure 1) of a schoolbus,
truck, emergency van, or other similar vehicle.
1.2 The speaker/ampliÞer is used in options for
Motorola XTVA, Vehicular Adapters, and other
similar products.
1.3 The
speaker/ampliÞer
bracket, hanger bracket, and wall mount bracket.
These brackets enable the speaker to be mounted
in a variety of different ways. Refer to Figure 1.
The trunnion bracket provides a large variety of
permanent mountings (dashboard and accessible
Þrewall areas) for the speaker, while permitting it
to be tilted or angled for best results.
The hanger bracket (already attached to the
speaker) by itself permits temporary mounting on
projections, such as automobile windows. In this
case, the speaker must be removed from its
trunnion bracket by loosening the two wing
screws.
The wall mount bracket can be used for permanent
mountings if the trunnion bracket is too large to Þt
in inaccessible areas. In this case, remove the
trunnion bracket and attach the speaker to the wall
mount bracket using the hanger bracket. Security
screws are included for optional use in place of
wing screws.
