System Maintenance Instructions
IR3xx-series Patient Station: Call cords may be replaced if a problem is encountered. To do so perform
the following steps:
1. To remove the call cord, firmly grip the plug and pull straight away from the patient station.
2. To insert the new call cord, hold the plug and push the end straight into the call cord jack on the
patient station.
3. Test the cord by pressing the button on the other end. This should initiate a call and light the
call indicator. Press the Reset button on the patient station to reset the call. Observe the station
for 10 seconds to ensure that no “cord-out” call occurs.
IR311 or IR312 Patient Station: Call cords and/or pillow speakers may be replaced if a problem is
encountered. To do so perform the following steps:
1. To remove the call cord or pillow speaker, firmly grip the plug and depress the locking tab. Pull
straight away from the patient station.
2. To insert the new call cord or pillow speaker, hold the plug and push the end straight onto the
call cord jack on the patient station.
3. Test the call cord or pillow speaker, respectively, by depressing the button on the other end or
the red nurse call button. This should initiate a call and light the call indicator. Press the Reset
button on the patient station to reset the call. Observe the station for 10 seconds to ensure that a
“cord-out” call does not occur.
LI380, LI384A and LI386 Dome/Zone Lights: Lamp bulbs must be replaced if they no longer light. To
do so, perform the following steps:
1. Remove the light cover lens by gripping it firmly, squeezing the sides and pulling it straight off
the base plate.
2. Remove the bulb by grasping the glass portion gently, so as not to break it. Push inwards, rotate
it counterclockwise, and pull it straight away from the metal socket.
3. If a color bulb cover is used, remove and transfer it to the new bulb.
4. Hold the new bulb by the glass portion gently, so as not to break it. Push it straight into the new
socket and rotate it clockwise.
5. Replace the cover lens.
6. Test the lamps by triggering the appropriate call to illuminate the new bulb (refer to the System
Operating Instructions on page 17 for details).
LI38xLED-series dome and zone lights use LEDs instead of incandescent lamps and therefore are not
replaceable. If one LED fails, replace the entire unit or return for repair.
