14.0 Taking Care of your handheld Transceiver 

 

Your transceiver has been designed using the latest in technology 

along with high temperature flame retardant plastics. Normal reg-

ular care an attention will increase the longevity of certain compo-

nents. 

 

 

Handle your radio with care. 

 

 

 Do not carry the transceiver by either the antenna or the   op-

tional external speaker microphone.  

 

 

When the speaker   microphone    or  other  accessory  is  not  in 

use, keep the  speaker microphone  accessory    jacks covered 

by using the supplied flap that is attached to the radio. 

 

 

To clean, use a moistened rag with a mild detergent, and with 

a  nearly  dried  cloth,  clean  the  case,  control  knobs,  and  key-

pad. Never use any chemicals to clean the unit. 

 

 

Regularly,  wipe  the  battery  contacts  with  a  lint-free  cloth  to 

remove dirt, grease, or any other materials that may prevent a 

good electrical connection. 

 

 

Never Expose the Radio to direct sunlight, heat or cold for ex-

tended periods of time. 

  

  

OPERATIONAL INSTRUCTIONS & SAFETY GUIDELINES 

 

RF  ENERGY  EXPOSURE  IS  DETERMINED  PRIMARILY  BY 

THE DISTANCE TO, AND THE POWER OF, THE TRANSMIT-

TING  DEVICE. 

In general, RF exposure is minimized when the low-

est possible power is used and transmission time is kept to a minimum 

consistent  with  effective  communications  and  the  antenna  is  at  the 

furthest  possible  distance  from  the  body.  Users  should  transmit  no 

more than 50% of the time and follow the guidelines:

 

 

To Transmit and Receive: You must be properly licensed by 

the FCC or your governing radio communications authority 

to use this radio on the programmed frequencies. 

 

To  Transmit

first  hold  down  the  MON  (Monitor)  button    if  so  pro-

grammed for a moment to make sure that the channel is not busy with 

other  traffic  that  you  may  not  hear  this  depending  on  the  TONE  that 

may be programmed in shared transceivers if the channel is a shared 

frequency with other users with different CTCSS/CDS Tones. You may 

also look at the received signal strength meter  (green light) is off) to 

ensure that the channel is clear. 

 

To transmit: Push and hold the Push–

 

to-Talk (PTT) Button; speak in a 

normal voice. There is a 1/4 second  delay  before the radio transmits 

as the RF output to the antenna is tuned to the frequency/channel be-

ing used. 

 

To Receive

release the PTT button.

 

 

Hand-held Transceiver Operation: 

Hold the radio in a vertical position with the radio approximately 1.5 to 

2.5 “ 

away from your lips. 

 

Body Worn Application: 

As in most cases whenever using an approved case and body pack for 

this transceiver or not, use of this radio with the antenna touching the 

body may exceed the FCC RF exposure guidelines.  

 

Antennas & Batteries 

Use only Infinity supplied and approved antennas and batteries. 

Use  of  non  approved  accessories  and  attachments  as  well  as 

user  modifications  could  not  only  damage  the  radio  and  void 

warranty, but also may void FCC  and CE regulations as well as 

 

exceed RF exposure limits.  DO NOT OVERCHARGE BATTER-

IES. Keeping the battery in the charger continually reduces bat-

tery life.  Consult Infinity or your Authorized Reseller/ Distributor 

 

if you have any questions.
