Why can’t I find a particular TLA100 tank level for display on Maretron’s DSM150, DSM200, or DSM250?

In order to keep the number of Maretron DSM150, DSM200, and DSM250 display menu items to a minimum (there is a possibility of more than 250 batteries, more than 250 engines, more than 250 tanks, etc.), the displays default to only few instances of tanks. If you don’t see the tank you are looking for, then:

1. Enter menu mode, scroll to to "Configuration..." and press
2. Scroll to "Data Enable/Disable..." and press
3. Scroll to "Tanks..." and press
4. Scroll to the desired tank type and press
5. Scroll to the desired tank number and press
6. Scroll to "On" and press
7. Press the key four times to exit menu mode and return to the normal viewing mode.
