    Additional Operations Setting Squelch Level An open (low) squelch level sets the threshold for the receiving signal strength to be low. This means that the radio would receive a great variety of signals, both weak and strong. A tighter (higher) squelch level raises the threshold, thus filtering weak signals and only accepting the stronger ones.

  • Page 52: Troubleshooting

    Troubleshooting Troubleshooting Radio is dead. Possible Problem (1): Batteries may be dead (alkaline) or not properly charged (NiCd). Solution :If the display does not light, or the ‘BATT’ indicator flashes on and off, you should replace the alkaline batteries, or if you are using NiCd batteries, recharge them.
  • Page 53 Troubleshooting Possible Problem (3): The battery life is based on a duty cycle where the radio is transmitting 5%, receiving 5%, and in standby mode 90% of the time. Usage that differs from this will change the typical battery life expect- ancy accordingly.
  • Page 54 Troubleshooting Radio will not talk to other radios in system. Possible Problem (1): Radios may be on different fre- quencies, having different Coded Squelch Codes. Solution :Verify that frequencies and Coded Squelch Codes are the same for all radios in your talk group. Hearing other conversations or noise on your radio.
  • Page 55 Troubleshooting Possible Problem (2): Operating the radio while it is close to your body (i.e. in a pocket or on a belt) and while you are using audio acces- sories decreases its range because of the shielding effect of your body. Solution :The higher the radio is held, the better the talk range.
  • Page 56 Possible Problem (1): The radio may need to be repaired. Solution :If the unit is still under warranty, return it to the place of purchase for repairs, or contact your nearest Motorola dealer listed in your local yellow pages.
