Setting up your MHM 100
Inserting and replacing batteries
To insert batteries, firstly ensure the MHM 100 is switched OFF and then
press the button at the back of the MHM 100 before sliding off the battery
cover.
Insert two AAA batteries as indicated by the ⊕ and symbols.
Only use high-quality batteries with a capacity of 600mAh or more, such as
‘Varta’, ‘Panasonic’, ‘Duracell’ or ‘Energizer’.
1. New batteries should be inserted for each 8 hour test
2. Do not mix battery types or new and partially used batteries
3. The MHM 100 does not allow a test to start if the batteries are running low
(i.e., if the low battery indicator is shown on the screen)
4. If the batteries run low during a test, the MHM 100 stops the test in order
to conserve battery power, in an attempt to avoid losing the test results
5. If the batteries run out completely, then the test results in the MHM 100
will be lost
6. The test results should be transferred onto the PC as soon as possible
after the end of a test, in case the batteries run out. (normally 24 to 36
hours)
7. All batteries should be disposed of responsibly
There is a battery indicator on the MHM 100 screen so that the user can see
when the power is getting low. Also, if the batteries are running low either at
the start of the test or during the test, the messages shown below will appear
advising them what to do. Note: The battery indicator is only visible when the
batteries are low.
If the batteries ‘run low’ during a test, a report can still be received as long as
the results are transferred to the computer immediately, however, bear in
mind that the report will be shorter than usual. However, if the batteries ‘run
out’ the report will be erased (lost). This should not happen if new batteries
are used for each test.
