1 Disclaimer
This document is intended as an enhanced version of the manual that comes with
the radio. It does describe all those details, that are required to know in order to
get the most out of your Radioddity DB25-D or GD-88. If you find anything that
needs correction or should be added, please let us know at:
support@radioddity.com.
For those new to DMR we advise to look at the document our engineers prepared
for them. Check the corresponding blog-entry for more details.
https://www.radioddity.com/blogs/all/radioddity-getting-on-air-with-your-dmr-radio
Those of you already familiar with analog and DMR operations, may just jump into
our chapter on ‘Quickstart for common use cases‘starting on page 181.
However, and although this manual is quite comprehensive, we do advise you to
read it all through. Especially DMR-operations may fail very easy if not all needed
parameters are set up as required.
In case something does not work as you´d expect it to, restart with a fresh and
new codeplug that only contains the minimum data required for the functionality
you think that is failing. If you still cannot get it working as expected, such minimal
codeplug and precise step by step instructions on how to reproduce your issue
makes it much easier for our support staff to get your issue sorted out. Our
support is available via support@radioddity.com only.
Windows™, Linux™ and OS X™ are the properties of their respective owners.
Should any trademark attribution be missing, mistaken or erroneous, please
contact us as soon as possible for rectification.
Not all functionality is available in both operating modes of the radio and for both
radios. For easier identification of those functionality, we used the following icons:
Parameter names, as displayed on the screen of the Radioddity DB25-D are
written bold&italic.
Described functionality is only available for digital DMR channels
Described functionality is only available for analog channels
The described function/feature is only available for the
Radioddity DB25-D.
The described function/feature is only available for the
Radioddity GD-88.

5 Prepare radio for operation
5.1 Radioddity DB25-D preparation and mounting
For sake of your own and passenger’s safety, please find a safe and convenient
position in order to prevent any damage caused by moving car. Check about
suitable and allowed positions with the manufacturer of your car. Choose a
mounting location within the driver's reach that allows a view of the radio and the
road ahead. The small size makes this more of a possibility than larger under dash
radios. Typical under dash installations rely on devices with direct functions and
controls. 2 step controls are harder to perform while keeping your eyes on the
road. You can consider installing the radio in front of the front passenger seat
below the panel section or the car trunk. This will prevent your knees and legs
crashing the radio in case of an emergency brake. You should install it with good
ventilation and avoiding the direct sunlight. Keep it away from locations with
inflating airbags.
1. Install the mounting bracket to the car using self-taping screws and flat washers
(2 pcs of each kind).
•Screws can be put upside down (under the dashboard mounting) or upwards
the mounting bracket.
•When installing the mounting bracket, please make sure the screw side edge
with slots on the bracket are facing backwards.
2. Next take the radio body and mount it between the two side wings of the
mounting bracket. Secure the radio body to the mounting bracket using the two
supplied M4 x 10mm Rack mounting screws including their fixed washers.
3. Please make sure all the screws are tight to prevent the radio's firm hold from
being lost due to vibrations in the car.
