11. BATTERY PACK REPLACEMENT
This procedure provides instructions for replacing
the battery pack. Refer to Figure 9 during the proce-
dure.
1.
Install the new battery assembly (9).
2.
Replace the battery bracket (8) and insert
the four screws (7) to hold the battery
bracket in place.
3.
Reattach the battery connector to J6 (6) on
the main RF PCB assembly (3).
4.
Set the bottom half in place.
5.
While holding the two halves together, turn
the Site Master over and lay it face up on the
work surface.
6.
Reinstall the four screws (2).
7.
Install the rubber bumpers (1) on all four
corners of the instrument.
NOTE
Corner bumpers can only mount one
way. That is, the raised-wedged area
on the bumper inside (Detail A) at-
taches to the front cover.
12. BATTERY DISPOSAL
The battery used in the Site Master is a recharge-
able nickel-cadmium (NiCd) battery and is covered
by the Battery Directive (91/157/EEC). As such, the
battery is marked as follows to indicate controlled
disposal.
This marking indicates that
the battery is a recyclable
product.
This marking indicates that
the battery requires separate
collection and shows the
chemical system (Nickel/
Cadmium).
This marking indicates the
heavy-metal component
concentration as a percentage
of battery cell weight.
Spent nickel-cadmium batteries are valuable re-
sources. Because they are reusable, do not throw
them away. Arrange for proper return for recycling
in your locality. If you do not have access to proper
disposal methods, return the battery pack to your
Anritsu service center. Service centers will dispose of
the unit at no charge. Anritsu service centers are
listed in Table 2 on page 13.
13. KEY PAD MEMBRANE REPLACEMENT
This procedure provides instructions for replacing
the key pad membrane. Refer to Figure 9 during the
procedure.
1.
Place the Site Master face up on a work sur-
face.
2.
Remove the four corner rubber bumpers (1).
3.
Remove the four screws (PN 900-811) (2).
4.
While holding the two halves of the Site
Master together, turn it over and set it face
down on the work surface.
CAUTION
In the next step, the PCB assembly
(3) and test port panel (4) must stay
with the front panel.
5.
Remove the bottom half (5) and fold it over to
lay upside down on the work surface.
6.
Disconnect the battery connector from J6 (6).
7.
Remove the screw (10) located on the bottom
side of the main PCB assembly next to the
RF Bridge assembly.
8.
Pull the PCB Assemblies clear from the top
half of the case.
9.
Lift the damaged keypad membrane clear
from the keypad assembly.
10.
Install a new membrane.
