Floating Radio
Burp Feature
Cobra’s
Burp
feature allows the operator to expel water from
inside the speaker grill. This is especially useful if the radio is
dropped overboard or during extreme foul weather
conditions. In these conditions, water can become trapped in
the speaker grill and muffle the audio.
To Activate Burp:
1.
Press and release the
16/9
and
SCAN
keys at the
same time.
2.
The
Burp
tone(s) at maximum level will sound
from the internal speaker for eight seconds.
3.
During this time, the matrix will display
BURP
.
4.
Hold the radio with the speaker grill down to help
the water drain out.
5.
After an 8-second interval, the radio will return to
standby.
Floating Radio
This radio is designed to float if dropped overboard. The
orange center makes it visible and easy to retrieve. This
rugged radio is also designed to meet JIS7 (IPX7)
specifications. This means it’s designed to operate properly
after being submerged in one meter deep water for 30
minutes.
NOTE
Do not leave the radio floating in water permanently.
This could cause premature corrosion of the battery
contacts and other damage.
The radio is only designed to float with its included
Lithium-ion battery. Using other approved batteries
might cause the radio to sink. This includes the optional
AA battery tray, depending on the weight of the AA
batteries used.

Maintenance
•
Very little maintenance is required to keep your CobraMarine VHF radio
in good operating condition:
■
Keep the radio and charger clean by wiping with a soft cloth and mild detergent.
Do not use solvents or harsh or abrasive cleaners, which could damage the case
or scratch the LCD screen.
■
If the radio is exposed to salt water, wipe with a soft, moist cloth at least once a
day to prevent buildup of salt deposits, which could interfere with button
operation.
■
If the radio will be stored for a long period, such as over the winter,
remove the batteries from the battery tray and store them in a separate
package. This is especially important if you are using alkaline batteries.
