EFJohnson FM Portable Radio Intrinsically-Safe SMARTNET Manual De Usuario

54

As noted several times in this manual, programming determines the 

availability and specific operation of many features. This refers to the 
programming performed by your dealer when the radio was set up, not to 
any programming that you can perform. If a feature is controlled by a 
front panel option switch and that switch is not available, it is probably 
not available or in a fixed condition. Contact your dealer for more infor-
mation on how programmable functions have been set for your 
application.

For best results, hold the speaker grille about 1-2 inches from your 

mouth and speak at a normal conversational level. Do not shout since it 
distorts your voice and does not increase range. Make sure that the PTT 
(push-to-talk) switch is pressed before you begin to speak and released as 
soon as the message is complete.

When approaching the limits of radio range, the other party may not 

be able to hear your transmissions and there may be an increase in back-
ground noise when messages are received. You may still be out of range 
even though you can hear a message. The reason for this is that the signal 
you are receiving is usually transmitted at a higher power level than the 
one transmitted by your transceiver. Communication may be improved by 
moving to higher ground or away from shielding objects such as tall 
buildings or hills.

A government license is usually required to operate this transceiver 

on the air. Your dealer will normally handle the licensing requirements.
