Technical Support - PM2 / PM2+ Monitor

Click on each issue to expand

e007, e008, e003 - Serious fault with micro-processor - Probable cause is a battery leak.

Replace the unit with a PM3 or PM4, as PM2 units are no longer manufactured.
e011 - Low power condition - Probable cause is a dying battery

Reset the unit via the following procedure:
PRESS and HOLD: RECALL, both SET DIGITS, and OK, then press and hold ON/OFF then release all 5 buttons. The unit should start to count up several times which ends when you see a 5 in the middle of the screen, from here press ON/OFF to complete the process and the unit should be back to normal.

Check the battery contacts:
- Are they complete or has any one of them broken?
- Is there any corrosion or battery leakage on them?
- Is there any missing completely?
Clean all the terminals with white spirit or computer solvent until corrosion is removed. Dry off any excess cleaning fluid.

The image on the right shows a severely corroded battery compartment where the PM2 is unrepairable.

In this case a replacement PM3 or PM4 unit is advised.
Check the circuit board for any corrosion:
- Has the battery leaked over any components?
- Is the inside slightly damp?
- Can you see any moisture on the inside casing?
Dry any dampness with a cloth, and scrub the circuit board with a small brush or toothbrush and white spirit or computer solvent.

The image on the right shows a severely corroded circuit board where the keypad contacts have been erroded by a battery leak, this PM2 is unrepairable. In this case a replacement PM3 or PM4 unit is advised.
Check the components:
- Have any of the legs snapped off the crystal oscillator?
- Has the diode D9 (or D6 on some boards) broken off?
Broken components need to be re-soldered or replaced
Check the keypad:
- Is the keypad really worn, (usually a good indicator as to how much use the monitor has had)?
Scrub the contacts of where the keypad fits onto the board, and replace the keypad.
Has all of the above has failed to cure the problem?

The monitor may be un-repairable. Return the unit to Concept2.

Check the LCD:
- Are the contacts along the edge of the LCD in tact or is any part of it cracked?
- Is the LCD the correct orientation?
- Is the correct LCD in place?
Replace the LCD with the correct type i.e. an EPM2 LCD for an EMP2 LCD.

The image on the right shows a smashed LCD possibly from the impact of the handle after a user has let go unexpectedly. In this case the LCD needs to be replaced and the circuit board inspected for any other impact damage.
Check the Case Front:
- Are the circuit board screw threads in tact?
This can make a great difference, if the screw threads are worn, then the LCD is not being pulled tight enough onto the board therefore not making sufficient contact. Replace the case front to cure the problem.
Has all of the above has failed to cure the problem?
The monitor may be un-repairable. Return the unit to Concept2.

Check the legs of the jack socket:
- Is there any lateral movement on the jack socket?
- Are the legs corroded with battery leakage or rust?
1. Sometimes it can be obvious that the jack socket needs replacing but other times when there is no reading it could be something internal in the jack unit, and by replacing it can cure the problem.
2. Clean the legs with white spirit and get rid of any corrosion.
Has all of the above has failed to cure the problem?
In this case it could be the pickup on the rower itself that is at fault. If not please return the unit to Concept2.
