•  After your radio is submerged in water, you might 

notice that the sound is distorted. This is because

we recommend you:

where the radio will get the best range.

•  Optimize range during the channel change 

signal by raising the radio over your head to 
give the best possible height.

move to be sure no one was left behind. If you 
missed someone, return to the previous channel 
and issue the signal again.

call.

missed call by vibrating every minute after the call 

for 3 minutes.
