Chapter 5 Dual-Radio Installation
5.1 Installation Planning
The ASTRO Digital XTL 5000 Dual Radio System consists of several different components (see
Figure 5-1) and some preliminary planning should be completed before beginning actual system
installation. The W3 Handheld Control Head (HHCH), emergency footswitch, and speakers mount in
the operator’s compartment. It is recommended that the radios be mounted in the vehicle’s trunk. Be
sure the chosen locations for all housings do not expose the units to dirt or moisture.
