Use scanning to monitor channels for transmissions or to find someone
in your group who has accidentally changed channels.
1. Short press MENU until the "Z" appears. The current setting
On/Off will flash.

Here is a link to the manual http://www.motorola.com/mdirect/manuals/FV200_userguide.pdf
Tesco does not list operating manuals on their web site, so I suggest that you contact them directly by following this link:
They should be able to provide you with the needed manual.
This one should be a very close match. The T4508 is a foreign version of the T4500.
I think you'll think this is fantastic: http://www.giantintl.com/ContentManage/manuals/Moto/T8500%20English%20only%20June5.pdf
If they are both the same model, make sure both the channel and ctcss codes match, as there can be 38 codes per channel, if they dont match u will not be able to communicate between them
that will show you how
hope this helps
You will find the manual here. The radio is part of the 280 series radios, so there is a general manual on all in that series.
