7 During programming, the pressure selection buttons will light sequentially until the
selected pressure setting is attained.
8 When programming is completed (approximately 2 seconds), the programmer will
emit a long beep sound and the display will change to:
PROGRAMMING
9 After a short wait, the LCD panel will change to the original message once again:
10 Use an x-ray with an intensifying TV screen, or an x-ray plate, to confirm proper
valve pressure.
When documenting the valve pressure with x-rays, take care when positioning the
patient's head so that:
• the nonimplanted side of the head rests on the plate (the implanted side is
uppermost from the plate), and,
• the inlet valve is parallel to the x-ray plate.
The Effect of Ambient Temperature on Valve Programming
Ambient temperature plays a major role in how many programming cycles can be
completed before the transmitter reaches the temperature shut-off point and the
message "TRANSMITTER COOLING PLEASE WAIT" is displayed. It also has an effect on
how quickly the transmitter will cool. In warm ambient environments, the programmer
reaches the temperature shut-off point much more quickly, and cools much more
slowly than in cooler ambient environments.
It is suggested that the programmer and transmitter be stored in a cool dry location.
Avoid storage in areas with high heat, such as automobile trunks or sunny windows.
CAUTION: The transmitter shut-off temperature has been chosen to assure patient
safety Do not place the transmitter in contact with the patient while the message
"TRANSMITTER COOLING PLEASE WAIT" is displayed
Programming Procedure in Case of an Inverted Valve
An inverted valve can be diagnosed on x-ray; the white marker will appear on the left
side of the valve, instead of the right side. Programming the inverted valve requires a
"double programming" to obtain the desired pressure setting.
1 Program the valve with the valve programmer at the 200 valve pressure setting.
2 Calculate the following: 210 (constant) minus the desired pressure setting equals
the programming pressure setting. For example, where 70 is the desired pressure
setting: 210 – 70 = 140.
3 Push the button for the programming pressure setting (in this example, 140) on the
programmer; hold the transmitter in place for approximately 2 seconds until the long
beep sound is heard.
If it is unclear whether reprogramming took place, repeat Steps 1 through 3, otherwise
the programming will be incorrect.
Note: When the valve is inverted, pressure settings of 190 and 200 are not possible to
program.

Troubleshooting
Symptom:
LCD panel displays the following message:
TRANSMITTER
DISCONNECTED
OR DAMAGED
Cause:
Transmitter is damaged or disconnected from programmer.
Solutions:
1 Reconnect transmitter to programmer.
2 Try another transmitter.
Symptom:
LCD panel displays the following message:
TRANSMITTER
Cause:
Transmitter temperature is too high. Too many programming
attempts in a short time period.
Solutions:
Allow transmitter to cool until the following message is displayed:
Symptom:
LCD panel displays the following message:
PROGRAMMING
Cause:
Error in transmitted programming signal.
Solutions:
When the following message appears, repeat program sequence:
Symptom:
LCD panel displays the following message:
PROGRAMMER
NEED SERVICE
Cause:
Internal malfunction in the programmer.
Solutions:
Return for service.
Symptom:
No LCD panel display; no LED illumination.
Cause:
Interruption in the power supply.
Solutions:
1 Replace fuse with correct value and type.
2 Check power cord connection; check that the power switch is on.
3 Check power (mains) supply integrity with a known functioning
device.
