Quick Start Guide

drivers, etc.).
• First and second maintenance level interventions on the equipment are to be car-ried
out by authorized technicians only.
• Third maintenance level interventions are to be carried out by CALTTA technicians only.
• Use only original accessories and spare parts, approved by the manufacturer, suit-able for
the PH690. The use of different accessories and/or spare parts (earphone,
antenna,etc.)makes the safety and electromagnetic compatibility certifications to be valid no
more and it could lower the user safety level and/or generate electromag-netic fields that
exceed the accepted limits.
• Follow the battery charger instructions in order to use it correctly.
• During voice calls, the PH690 use with its proper bag is not recommended in envi-
ronments which temperature can be over 45°C.
• The emergency call is a priority type call. The portable radio, like all mobile telepho-ny
equipment, operates with radio frequency signals, therefore, the forwarding of the call
depends on the network coverage during the call.
• If you need send an emergency call, keep pressing the emergency button for at least
2 seconds, when the radio is switched on.
• Do not cause short circuits between the battery terminals. Do not set the batteries on
metal surfaces. Do not set metal tools on the battery terminals. Be careful when handling
ant battery, when placing it in a pocket, purse/bag or any other.
• Do not use the battery charger if the power supply cable and/or the plug are dam-aged.
• If the battery is incorrectly replaced existing the dangerous risk of explosion.
• Even if the battery is discharge, the risk of explosion exists if the battery is disposed on fire.
• Do not take the radio into environments that have a potentially explosive atmo-sphere(ex.
fuel storage sites, filling stations,etc.). Even when it is off, the radio, being equipped with
battery, might casually generate sparks that could trigger fires and/or explosions.
• Do not use the battery charger in environments that have a potentially explosive
atmosphere(ex. fuel storage sites, filling stations,etc.). The use of battery charger might
generate sparks that could trigger fires and/or explosions.
• In order to further increase the level of user safety, you have to observe the follow-ing
precautions:
• The PH690 radio is equipped with an automatic system to control the power trans-mitted so
that the radio transmits at the maximum power only in exceptional cases (radio coverage
limit, emergency call). Avoid touching the antenna when the radio is on and especially
during transmission because the ability of transmitting power gets worse.
• During voice communications in earphone mode hold the portable radio with the antenna
straight and above your shoulder and speak directly into the microphone.
• Hold the portable radio in the vertical position and always at least 2.5 cm away from
