SLEEP
 on page 21.
Continuous Tone Coded Squelch System
Selective squelch opening by sub-tone detection (CTCSS) can be enabled, 
using the configuration mode (see 
CTCSS
 on page 24). Please note that if 
the radio is operating with CTCSS on a channel, and a carrier is received, 
it may not be recognized in the loud speaker if the matching sub-tone is 
not detected. For this reason, be very careful not to use CTCSS 
programmed channels in emergency situations. For the same reason 
0845

Operation
12
transmitting is prohibited (reporting "BUSY") if a (silent) carrier 
containing any sub-tone is active on the channel while pressing PTT.
Channels programmed with CTCSS will have a clear identification in the 
service field, e.g. "CTCSS 22", while selected. Not all channels are allowed 
for CTCSS use. 
In maritime channel modes CTCSS is automatically disabled when 
• Product is turned off 
• A new channel is selected
For private channels and ALT channel mode, the feature will remain until 
manually removed.
Scrambler
On channels where it is allowed, you can set up voice scrambling, using 
configuration mode (see 
SCRM
 on page 25). 
Please note that if the radio is operating with scrambling on a channel, it 
is impossible to communicate with other radios that are not programmed 
with the same scrambler code. For this reason, be very careful not to use 
scrambled channels in emergency situations. Scrambled channels will 
have a clear identification in the service field, e.g. "SCRM 3", while 
selected. Not all regions allow the use of voice scrambling.
In maritime channel modes scrambling is automatically disabled when
• Product is turned off 
• A new channel is selected
For private channels and ALT channel mode, scrambling will remain until 
manually removed.
0845

Operation
13
Narrow band operation
The radio is prepared for narrow band operation. If narrow band 
operation is selected (see 
BAND
 on page 25), the number of channels are 
doubled in the maritime channels, according to international 
recommendations. Refer to the channel table in 
Channels
 on page 2. 
Channels are clearly identified with a preceding 4- or 2-digit, while 
operating in narrow band mode. Narrow band radios will not always be 
completely compatible with wide band operating radios.
For single narrow band configured private channels or "ALT" channels, 
an “n” is displayed next to the channel designator.
Note Prior to any initiation of scrambling, the operator must always 
identify the calling station in clear voice (unscrambled) on that 
channel. Use of scrambling may also be restricted by national 
laws.

Battery life guidelines
During daily use, always keep the battery fully charged and away from 
hot areas.
Keep the battery terminals dry and clean.
Never discharge beyond the specifications of the battery.
Operation/Standby time depends on usage. Generally, the more the radio 
is transmitting, the faster it will drain the battery. Also, the “Hi” power 
setting will drain the battery faster than the “Lo” setting.
Approximate figures are:
• A battery can be stored for 4 to 6 month at 25°C if charged to 25%.
• The battery will normally last for 5 to 9 hours of use on a fully 
charged battery. 
Note New batteries should be placed in the charger CH3507B or 
CH3508B for minimum 12 hours first time.
