SECTION 5
5.1
WARNING: To reduce the risk of electric shock, do not attempt any servicing or
repairs unless you are qualified to do so. Refer all servicing or repairs to an
authorised PAG service centre. The charger contains advanced electronics that
do not require periodic maintenance. Consequently there are no user-
serviceable parts inside.
5.2
Qualified electronics engineers who wish to gain access to internal assemblies
should note that parts of the power circuit retain a high voltage even after the
mains supply has been disconnected. Wait for a period of five minutes following
disconnection before commencing disassembly, and be aware of charged
capacitors.
5.3
When the charger is correctly connected to an AC supply and the display is
not functioning, it may be that a supply fuse has become open circuit.
Equipment supplied for use in the UK is supplied with a standard UK AC power
lead, complete with a moulded, fused plug. If this fuse has become open circuit
it should be replaced by another of the correct rating (see 'Specification'
section 2.12). USE ONLY A FUSE OF THE CORRECT RATING. If the replacement of
the fuse fails to correct the above symptoms, do not attempt further fuse
replacement. It is likely that a fault has developed. Seek advice from PAG Ltd.
by telephoning +44 (0)20 8543 3131, or email: support@paguk.com.
5.4
PAG RMC4X chargers feature a fail-safe shutdown mode. In the unlikely event
of an internal malfunction, an error message will be displayed on the screen,
see 4.15 above. This could be the result of any number of undesirable
situations from which the system is protecting itself, such as the obstruction of
ventilation slots, causing inadequate cooling, or the microcomputer's detection
of an internal fault. In these cases the charger should be disconnected from the
supply, any obstruction of the air vent system removed, and the unit allowed to
cool before reconnecting to the supply. Should the charger re-enter the fail-
safe shutdown mode, more detailed investigation is required. Make a note of
the error message and seek advice from PAG Ltd. by telephoning +44 (0)20
8543 3131, or email: support@paguk.com.
5.5
Unqualified personnel should not attempt further investigation (see paragraph
5.1 above). Any such interference would invalidate the guarantee and invariably
cause more damage than the original fault.
