The Private Mobile Radio Story
A1
The Private Mobile Radio Story
Ever wish you could talk to someone who wasn’t
within earshot? Like contacting ski partners back
at the lodge? Or letting a friend know how to find
you in a busy shopping centre? Cobra’s MicroTalk
radios are a great way for friends or family to
increase their fun - and safety - by staying in touch
while on the go and they are perfectfor business
use as well,such as office to warehouse communi-
cations.
The ERC (European Radiocommunications
Committee) has created 8 channels,called Private
Mobile Radio (PMR). These channels are in the
UHF (Ultra High Frequency) band which means
great penetration through buildings,thick forests,
hills,and other dense structures.They are also FM
(Frequency Modulation) signals which means
crystal-clear reception even in crowded noisy
environments.
Included with your MicroTalk
1. Removable Belt Clip
2. Wrist Strap
