dm8
Troubleshooting
The dm8 contains no user serviceable parts inside the compartments. Do not attempt to open
the unit as this will void the warranty and will expose you to dangerous voltages. For all
service requirements please contact your dealer or email HALCRO™ at [e-mail]
If the dm8 does not operate as expected first switch the dm8 back to Stand-by and then switch
the main power switch off. Once the display has turned off switch the main power switch
back on and then switch the unit from Stand-by to On. This will reset the microprocessors in
the dm8.
