To switch the ASV 3270 off, hold the Mode button down for more than 3 seconds until the LEDs switch off. Auto Power Off If the Mode button on the ASV 3270 is not operated for more than approximately 5 minutes, it will switch itself off to conserve the battery. -

12V (or 24V) and probe the wire of interest with the black lead. CAUTION: In order to minimise the risk of damage to the electronic equipment found in modern cars, the ASV 3270's input impedance in voltage test mode is quite high (approximately 48000 Ohms). - Page 7 Line Output Tone. Using a 3.5mm to RCA lead, connect the ASV 3270 to the input of an amplifier you want to test. In this mode, the ASV 3270 outputs a nominal line level signal. CAUTION: Make sure the gain of the amplifier under test is set...
- Page 8 Once you have downloaded the file and created the required media, start playing the file in the head unit at a moderate volume. Connect the ASV 3270 to a pair of speaker wires. If LED A lights, the speaker wire connected to the red test lead is positive.
- Page 9 DC current at 200mA to enable testing of speakers. CAUTION: Do not probe random wires while in this mode. The ASV 3270 outputs 200mA of current at up to 9V, which may damage some of the sensitive circuits in a modern vehicle.
- Page 10 Testing Battery Condition When switching on the ASV 3270, the 4 mode LEDs give an indication of battery status while the Mode button is depressed. If all 4 LEDs illuminate, there is plenty of charge remaining. The number of LEDs will decrease according to the remaining capacity.
