SmartPhone hangs up after the call is answered:
• SmartPhone may be in the wrong mode. Verify the phone is in Standard Mode. See the “Reset” section to reset
the phones.
• There may be excessive noise on the phone line. Connect an analog phone to the line and place a call. After
placing a call, listen for any interference (buzzing, humming, etc.). If interference is heard, the phone line must be
cleaned up.
• Verify the phone line going into the SmartPhone is dedicated. SmartPhones cannot share a phone line with
anything other than another SmartPhone.
SmartPhone doesn’t operate when the external elevator power is killed:
• Verify that the backup battery has at least 7.3vdc on it. When batteries are fully charged, they will have up to 9.2vdc.
• Check “Replace By” date on the sticker wrapped around the battery cord. Batteries should be replaced every 3 years.
SmartPhone has poor two-way communication:
• Speaker and mic may be turned up too high. Adjust VR1 and VR2 on the board counterclockwise to decrease.
• Speaker may not be aligned with the holes on the panel. Verify speaker is mounted so it lines up with the panel.
• Microphone may not be aligned with the holes on the panel. Verify microphone is mounted so that it lines up with
the panel. If using a SmartPhone where the microphone is mounted in a mounting bracket below the board, pull
microphone out so it doesn’t sit as far into the mounting bracket.
• Verify nothing is blocking or covering the holes on the panel.
SmartPhone starts buzzing as soon as input power is connected:
• Backup battery needs to be connected.
• Wrong input power is connected to the board. 24v boards will buzz when 12v is connected, 12v boards will buzz
when 24v is connected.
• Speaker and microphone may be feeding back into one another. VR1 and VR2 may need to be adjusted down.
See “Volume Adjustment” section for location of VR1 and VR2.
SmartPhone keeps “ghost dialing” the monitoring location:
• Phone may be installed on a Ring Down style phone line and the Line Check on the phone is turned on. See
“Detailed Programming” section to modify this feature.
• Call wasn’t hung up properly. Verify that the operator is pressing
*, #
when the call is complete or that there is a
disconnect signal on the phone line.
• Another device is sharing the phone line with the SmartPhone.
• The button connected to the phone may be shorted or wired incorrectly.
