GP308 KEY FEATURES AND BENEFITS:
X-Pand Audio Technology
Motorola special voice compression and expansion
technologycalledX-PANDenables crisper, clearer and
strongeraudioquality,allowingmessages to be heard
even in a high noise environment.
Wide Band
Onlyonemodelisrequiredineach individual frequency
band:–136-174 MHz, 403-470MHz,450-527 MHz, the
radioallowsuserstheflexibilitytoselecttheirfrequency
for use in their respective work environment without
theneedtobuydifferentfrequencymodels.Thusreduce
inventory cost and improve delivery cycle time.
Adjustable Power Level
Userscan switch toa low powerwhen communicating
withinlimitedrangecoverage orswitchtoahighpower
level when further distance is required. High transmit
power maximise range coverage while low transmit
power conserve battery consumption, all at the user’s
control.
Programmable Channel Spacing Of 12.5kHz/25
kHz Mode
Flexibleandeasy migrationof multiplechannel spacing
of 12.5kHz, 20kHz, 25kHz within one radio means you
do not need to purchase a new radio, protecting your
investment as should your country’s regulatory
requirement changes.
Repeater Talk Around
Users have the freedom to communicate through a
repeater for wide area coverage, or bypass a repeater
and talk directly to another radio if the coverage is
within the range or when the repeater malfunctions.
Tight/Normal Squelch
The radio’s sensitivity can be regulated by selecting
theappropriatesquelchlevels.Usershavetheflexibility
to protect their communication by switching to tight
squelch to filter out interference of unwanted weak
signal; or normal squelch to increase coverage.
Cloning Operation
Easy transfer of essential operating features from one
radiotoanother through a cloning cable without using
computerstoreprogrammetheradios,enablesimproved
efficiency.
Rapid Charger
A new 90-minute time saving rapid charger helps to
improve productivity. This charger can also be used to
charge both NiMH and NiCD battery. One charger fits
all–Value for your money!
