5. Adjust Audio Volume
Speaker volume pot VR1 may have to be adjusted for proper operation of the Crown Jewel.
Set the speaker volume pot as follows:
♦ The factory setting is indicated by a mark on the rim of the pot.
♦ To turn the speaker volume up, turn the adjustment pot clockwise.
♦ To turn the speaker volume down, turn the adjustment pot counter-clockwise.
1. Place a call to the tenant and ask them to speak.
2. While they are speaking, listen to theCrown Jewel's speaker volume.
3. If the speaker volume is either too loud or too soft, adjust speaker volume pot VR1 on the main
processor board (see Figure 14).
4. When the speaker volume is set to the desired level, end the call.
6. Verify Telephone Connections
If you have a telephone test set (also known as a "buttset") with a monitor mode, you can test
the connection to the resident's telephone using the following procedure:
1. Make sure the test set is in monitoring mode.
2. Connect the test set clips to the pins marked "TELCO" on the bypass board (see Figure 15).
Make sure a dial tone is emitted from the test set.
3. Connect the test set clips to the pins marked "HOME" on the bypass board (see Figure 15).
Make sure a dial tone is emitted from the test set.
If you do not have access to a telephone test set, test the connection to the resident's
telephone as follows:
1. Have someone make a normal phone call from the resident's telephone to verify it is operating
properly, then hang up the phone.
2. Press the "# " key on the Crown Jewel keypad. The telephone in the residence should ring.
3. Have someone answer the phone and dial a "9". The door/gate control relays should activate.
