Communicate with friends, family or work colleagues with this handy pair of rechargeable 80 Channel UHF Transceivers. They include many features you usually only find on more expensive models, including backlit LCD, monitor, call tones, roger beep, child lock, VOX hands-free function, and 38 CTSS sub channels to reduce interference on congested channels. There is also an LED built-in to find your way in the dark, and a 2.5mm earpiece jack to plug in a headset mic (not included). When not in use, the Ni-MH rechargeable batteries are kept topped up in the supplied charging cradle. When you are away from the charger, a battery save function helps to extend battery life, and regular Alkaline AAA batteries can also be used to keep the unit operating.
