Troubleshooting; Specifications - ATN MO4-HPT User Manual

• Do not disassemble except to clean the front lens and eyepiece, install the 6x Doubler or any
other "C" mount lens: it will void your warranty.
• Evaluate the scopes function by looking through it in a lit environment with the daylight filter
lens cap on. Never use in daylight without the daylight filter lens.
• never point the MO-4 at a bright light source.
• Adverse atmospheric conditions such as fog, smog or haze and a lack of ambient light (moon
or starlight) may diminish the effective viewing distance.
