Edwards Signaling 99B - Manual (Page 3)

P-047550-1300 ISSUE 5
Non-magnetic surfaces: Refer to Figure 3. A steel circular disk
is supplied with the 99B series signals to provide for mounting
this signal to non-magnetic horizontal surfaces as dashboards.
The disk has a piece of Velcro permanently affixed to one side. A
second piece of paper backed Velcro is attached to the disk-Velcro
assembly. Remove the paper backed Velcro from the disk-Velcro
assembly and remove its paper backing. Press the sticky side of
the Velcro onto the dash or other suitable surface. Next, attach
the disk-Velcro assembly to the Velcro on the dash.
Mount the 99B signal on the steel circular disk (of the disk-Velcro
assembly) and insert the adapter plug into the vehicle’s cigarette
lighter socket.
To dismount the signal, remove the adapter plug from the ciga-
rette lighter. Next, to prevent removing the disk-Velcro assembly
when removing the 99B signal, press down firmly on the edge of
the disk assembly (the assembly is slightly larger than the mag-
netic mounting base) and tip the signal slightly before breaking
magnetic contact with the disk.
Troubleshooting
96B and 98B Signals: If the strobe light fails to operate, make
sure there is power to the signal. If there is power and the strobe
still fails to operate, replace the strobe tube as directed in the
“Strobe Tube Replacement” section.
99B Signals: If the strobe light fails to operate:
a. Verify that the adapter plug is firmly inserted into the cigarette
lighter socket.
b. Rotate the adapter plug a few times to remove possible ash
accumulation from the contacts in the cigarette lighter socket.
If the strobe still fails to operate, remove the fuse for the
cigarette lighter and clean the socket and contact surfaces.
Replace the fuse and check the signal again.
If the strobe still fails to operate, replace the strobe tube as di-
rected in the “Strobe Tube Replacement” section.
Maintenance
Strobe Tube Replacement
Refer to the “Replacement Parts” section below for the required
type of strobe tube. After disconnecting power, replace the strobe
tube as follows:
Refer to Figure 4
1. Insert a small flat blade screwdriver between the locking
mechanism and the lens. Gently push down and then pry
up, unseating the lens. Pull the lens up and off of the signal
mounting base, being careful not to damage the lamp.

WARNINGS
To prevent electrical shock, ensure that power is
disconnected before installing the signal.
To prevent leakage and potential electrical shock,
use care when disassembling the signal to prevent
tearing of the permanently affixed gaskets provided
for weatherproofing.
Cleaning
CAUTION
To prevent damage to the lens, do not use abrasive
materials or cleaners.
Periodically clean the Adaptabeacon lens surface to maintain op-
timum light visibility. The lens may be cleaned with a soft cloth
or sponge using water or a mild detergent solution. Ensure that
the lens is completely dry before assembling the signal.
CAUTION
To prevent damage to the strobe tube, handle the
tube only by the base.
