The standard service menu is activated with code 1100 . It allows to adjust the calibration gas
concentration and, with model CC28 DA, all values which are related to alarms.
The extended service menu is activated with code 5050 . It allows to also change the type of gas,
full scale and ambiguity alarm. This code should only be used by specially trained safety personnel.
Activation of the extended service menu is only possible, if it has been authorized by GfG during the
basic setting of the transmitter.
!
For transmitters with function test (labelling BVS 05 ATEX G 001 X): The extended
service menu allows adjustments which may become the function test void !
If the full scale value of 100 % LEL is changed to a different value, or if the gas is
changed from a certified gas (see page 3) to a non-certified one, the function test becomes
invalid.
