You may clean the optical filters by wiping them gently with lens paper and 70% ethanol. You
may obtain lens paper and lens cleaning solution by ordering a Lens Cleaning Kit from Bio-Rad
(catalog #170-7731). After cleaning both sides of an optical filter, hold it up to the light and make
sure that no smudges, fingerprints, debris, or water marks remain. Once cleaned, reinsert the
optical filters as described above.
9.3 Replacing the Lamp
When replacing the lamp, you must only use lamps supplied by Bio-Rad. Bio-Rad lamps are
subject to additional tests and standards geared specifically toward real-time data collection.
Lamps from alternative sources, which may appear to be similar, may not deliver the same optical
quality, performance, and lifetime as those supplied by Bio-Rad. If the camera is to remain
continuously on, we recommend the lamp be replaced every 6 months.
NOTE: When a lamp is overdue for replacement, if may flicker sporadically, causing a wavering of
the data in all wells simultaneously. Installing a new lamp will alleviate this problem.
Caution: Take care when changing the lamp as it may be hot. Allow at least 15 minutes after
turning off the MyiQ2, MyiQ or iQ5 camera module before removing the lamp.
Lamp Replacement Procedure
1. Turn off the power to the optical module.
2. Reach behind the optical module and unscrew the short fastener that secures the lid of
the module in place.
3. Using a gentle pressure with both hands, push inward on the rear vents located on the
top half of the instrument casing. Lift upward to remove the cover of the optical module.
4. The lamp is located on the right side of the optical module. Push up on the lamp spring
clip to release the lamp from the bracket.
5. Lift the lamp out of the socket.
6. Install the new lamp using the reverse of steps 1–5. Hold the new lamp by the outer
reflector and do not touch the bulb. Be sure the spring clip is down before inserting the
lamp into the socket. Push the lamp firmly into the bracket, then close the case and
secure the lid.
