5. Servicing
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 qualified servicing personnel. The charger
contains advanced electronics that do not require periodic mainte-
nance. 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 power 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 for use in the UK is supplied with a standard
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 3.11).
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. Contact your nearest authorised PAG

5.4
The chargers feature a fail-safe shutdown mode. In the unlikely event
of an internal malfunction, an error message will be displayed on the
screen. 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 your nearest authorsied PAG
Service Centre.
5.5
Unqualified personnel should not attempt further investigation (see
paragraph 5.1 above). Any such interference would invalidate the
guarantee and could cause more damage than the original fault.
