INTRODUCTION Pathmaker is a voice-oriented, handheld radio communications device providing groups of users with unlimited mobility and coverage without the need for a fixed infrastructure. By creating an ad hoc, self-routing mobile network, Pathmaker ensures high quality voice, data, and video communications together with simultaneous connectivity to external networks. Pathmaker offers a simultaneous voice and data wireless mesh network at the end unit level (radio device, cell phone/PDA, etc.).
General Information Pathmaker Network Radios provide dynamic wireless, mobile, ad-hoc networking communications without reliance on network infrastructure. Pathmaker Radio users become their own network, which makes the radios ideal for use in remote locations where no infrastructure exists or where the infrastructure has been destroyed or overloaded.
Do not cause short circuits between the battery terminals. Do not place the batteries on metal surfaces. Do not place metal tools on the battery terminals. Do not place battery in a pocket, purse/bag, or any other container with metal objects. Replace the batteries with equivalent batteries approved by the manufacturer. When replacing the batteries, follow the instructions given in the relevant technical manual. Do not use batteries that are not damaged, have liquid leaks or evident gaseous emissions.
Power the radio off before entering environments which have a potentially explosive atmosphere (ex. fuel storage sites, filling stations, etc.). Do not remove or replace the battery while in environments which have a potentially explosive atmosphere (ex. fuel storage sites, filling stations, etc.). Do not use the battery charger in environments which have a potentially explosive atmosphere (ex. fuel storage sites, filling stations, etc.).
Modes and Features • • • • • • • • Simultaneous voice, data, and video communications.

System Pathmaker type radios automatically create a self-configuring network without the need for any fixed infrastructure or base station sites. Each unit automatically acts as a relay station to other radios if this is required by their deployment pattern and mobility paths. Pathmaker Network Radios provide a dynamic wireless, mobile, ad-hoc, automatic, self organized RF mesh network without reliance on network infrastructure.

SETUP Normal setup includes unpacking, inspecting for damage, and charging the battery. Other setup procedures specific to a particular operating mode are included in the Operation section of this manual. Unpacking Inspect the hardware for damage. Retain the packing material and the shipping container, if desired, for possible future use.
Figure 3 - Charging the Battery The LED is normally off when the charger is plugged in and no radio or battery is installed. If the LED does not illuminate at all when the radio or battery is installed, check AC power or try reseating the radio or battery. If the LED illuminates flashing RED at any time, the charger is defective and should be replaced. Precautions • Keep the charger in a well ventilated, dry place. • Do not use the charger with any other batteries.
