* There are 2 different lens assemblies for KHS-400B and KHS-400C, which require different calibration data for MechaCon: T487 (white ring around lens) and T609K (yellow ring around lens). T609K seemingly was introduced with the D/D'-chassis. Some T609K have a white ring around the lens. These pickups may have a violet marking at the adjustment screw (Markings in other colors don't indicate any lens assembly variant, only violet does). Alternatively, they might also have "609" hand-written on their base. | * There are 2 different lens assemblies for KHS-400B and KHS-400C, which require different calibration data for MechaCon: T487 (white ring around lens) and T609K (yellow ring around lens).

Laser output power is actually regulated in real time by the drive electronics (APC | The two 2-kOhms potentiometers on the pickups (one for each, CD and DVD) do not directly adjust laser output power. Laser output power is actually regulated in real time by the drive electronics (APC). Instead, these potentiometers adjust the output level of the monitoring photodiode which the drive electronics uses for monitoring the laser output power. Hence, any weakening of the laser output power over time is already being compensated by the drive electronics. '''This means that adjusting these potentiometers should never be necessary.''' The only way of properly adjusting these potentiometers would be by using a laser power meter, which would however only be necessary in case someone already tinkered with the potentiometers. | ||
What turning these potentiometers actually does is overdriving the laser to higher than specified output power. The reason why this might allow discs to be read again is that it gives the drive higher tolerance to dirt on or inside the pickup's lens/prism system and/or misadjusted drive mechanics (tilt/skew). | What turning these potentiometers actually does is overdriving the laser to higher than specified output power.

KHS-400A, KHS-400B and KHS-400C have the current needed for driving the laser diode to achieve the specified light emission printed on their labels. E.g. "D565 C668" means 56.5 mA for the DVD laser diode and 66.8 mA for the CD laser diode. These values vary for each individual unit and are also based off the condition the laser was in directly after manufacturing, not after decades of use. | KHS-400A, KHS-400B and KHS-400C have the current needed for driving the laser diode to achieve the specified light emission printed on their labels.
