The GP350 VHF and UHF Portable radios use the Motorola 68HC11A8 microcomputer, U401, which utilizes: • 7.9488 MHz clock rate • Multiplexed 8-bit address/data lines • 16-bit addressing • Internal watchdog circuitry • Analog to digital conversion input ports The microcomputer’s operating program is permanently written or “masked” within the microcomputer. Included in U401 is an EEPROM memory which stores channel, signal- ling, and scan list information. When you are in the vicinity of construction work, look for, and observe, signs cautioning against radio transmission. If radio transmission is prohibited, you must not transmit until out of the area. Furthermore, you must turn off your radio to prevent any accidental transmission.
GP350 Standard radio package included:
1200 mAH NiCD rechargeable battery
10-hour drop-in charger
3" spring action belt clip
Heliflex or Whip antenna
1 year warranty
hold the radio with the antenna very close to, or touching, exposed parts of the body, especially the face, ears, or eyes, while transmitting. Hold the radio in a vertical position with the microphone two to three inches away from the lips.
hold the transmit switch (PTT) on when not actually desiring to transmit.
allow children to play with any radio equipment containing a transmitter.
operate this equipment near electrical blasting caps or in an explosive atmosphere. Under certain conditions, radios can interfere with blasting operations.
replace or charge batteries in a hazardous atmosphere. Contact sparking may occur while installing or removing batteries and cause an explosion.
• Turn radio off when removing or installing a battery.
