how to change hour meter in gaurded access?

Cylcles off, all units, power on, do this as soon as you switch on, must not go to start sequence.

(SBIII/SB300/400 UP type controller) press TK and clear buttons, scroll to hourmeter use up/down keys to wind back to zero. Then code and clear whilst in guarded access.

(SL200e/RDIISR MP/MPT type controller) go to DDR 45 press TK button, same as above, then scroll thru to alarm 71 shows and clear.

to turn the hourmeter on on these two first screen will say 0 change it to 2
to change the limit, second screen, change it to what you want

on SR2. Menu, alarms, press key with blank above it and then exit key and hold, same, then exit hourmeters, scroll to last screen. Press key with blank above it and exit key and hold, goto alarms and clear code 128 service due. The hourmeter set up is also in this Super guarded access screen.
Don't mess with anything else here, as the unit will malfunction if you don't know what your doing.
