5.3.11 Not indicated for patients taking Accutane (Isotretinoin)
currently or within the last 6 months.
5.3.12 Use of this device is not recommended for patients who
suffer from light-induced seizures.
5.3.13 Use of this device on pregnant women has not been
studied. Avoid usage on pregnant women.
5.3.14 Do not use this device for procedures other than those
proscribed in this manual. See Section 9.
5.3.15 make sure the disposable tip is fully seated onto the
handpiece before continuing with the procedure.
5.4 NOMINAL OCULAR HAZARD DISTANCE (NOHD)
The NOHD is the distance beyond which the exposure, during
normal operation, is not to exceed the appropriate Maximum
Permissible Exposure (MPE). The NOHD for persons wearing safety
glasses is shown in Table 1 below. The Nominal Hazard Zone (NHZ)
is the area where, the laser source within, which exposure levels
exceeds the MPE (which is the highest level of laser radiation to
which a person may be exposed without hazardous effects or
adverse biological changes in the eyes or skin). The outer limit of
the NHZ is the NOHD. Eye Protection within the NHZ is mandatory.
(See Table 1 below)
NOTE: This equipment has been tested and found to comply with
the limits for a Class A digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated
in a commercial environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause
harmful interference to radio communications. (Operation of
this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the
interference at their own expense).
