FORD 1999 F-550 v.1 - Manual (Page 80)

Replacing the battery
The transmitter is powered by one coin type three-volt lithium battery
CR2032 or equivalent. Typical operating range will allow you to be up to
10 meters (33 feet) away from your vehicle. A decrease in operating
range can be caused by:
• weather conditions
• nearby radio towers
• structures around the vehicle
• other vehicles parked next to the vehicle
To replace the battery:
1. Twist a thin coin between the two
halves of the transmitter near the
key ring. DO NOT TAKE THE
FRONT PART OF THE
TRANSMITTER APART.
2. Place the positive (+) side of new
battery in the same orientation.
Refer to the diagram inside the
transmitter unit.
3. Snap the two halves back
together.
Illuminated entry
The interior lamps illuminate when the remote entry system is used to
unlock the door(s) or sound the personal alarm.
The system automatically turns off after 25 seconds or when the ignition
is turned to the RUN or ACC position. The dome lamp control (if
equipped) must not be set to the OFF position for the illuminated entry
system to operate.
The inside lights will not turn off if:
• they have been turned on with the dimmer control or
• any door is open.
The battery saver will shut off the interior lamps 40 minutes after the
ignition has been turned to the OFF position.
