3. At Wave-Viewer, Select: Config Mode

4. At Wave-Viewer, Select: Setup and password: 14432

5. At Wave-Viewer, Select: Change Frequency

6. At Wave-Viewer, Enter the new frequency and check code.

7. At Wave-Viewer, Verify the new configuration of the transmitter.. if

applicable. (Ie… Sp02 configuration, etc..)


At this time, you must learn the new transmitter’s OSCAR ID via the PIC through the following menus.


From PIC in Standard Display (Main Screen) Select:

  1. Select: Patient window
  2. Select: All Controls
  3. Select: Unit Settings
  4. Under Bedside Unit Settings, Select: Telemetry Freq and password: m3150

  1. Press the key labeled INSTRUMENT CONFIG.
  3. Enter the following pass code 14432.
  4. The screen being displayed for you now is a list of all of the channels for that central. Each channel represents a sector on your screen.

  6. The first thing to do is enter the down converted frequency value for that channel. The formula to find this frequency is as follows:

(Transmitter operating frequency)- (Option number of down converter)

Example: Transmitter frequency of 608.5625Mhz with a down converter option number 148 would give you a receiver frequency of 460.5625Mhz

  1. After entering the frequency you need press CONFIRM.
  2. Now the system is asking you for you check code. Each frequency has a check code assigned to it by Philips. Find the corresponding check code for your receiver frequency and enter it now.
  3. Press CONFIRM.

  5. Put a known good battery in your transmitter and connect transmitter to a patient simulator.
  6. Now press the key labeled LEARN CODE.
