7. How to open the instrument
Use a flat screwdriver to unlock clips 'D', C', 'B'
and 'A', in this order. Remove the front filter.
75 (2.95)
Gently let the internal boards slide out of the
instrument.
To reinsert the boards in the housing :
8 (0.31)
1. make sure that the boards are correctly con-
nected to the displays pins
2. slide the boards into the housing guides
3. place the front filter at corner X, and then
insert clips 'A', 'B', 'C' and 'D' in this order.
Risk of electric shock. Removing the front cover will grant access to internal
circuits which may be at dangerous voltage. Disconnect the input signal and
the power supply to prevent electric shock to the operator. Operation must be
performed by qualified personnel only.
