A228/A248/A228I/A248I User’s manual
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be considered.
If the measured field strength in the location in which the model A228/A248/A228I/A248I is used
exceeds the applicable RF compliance level above, the model A228/A248/A228I/A248I should
be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the model
A228/A248/A228I/A248I.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
CLEANING/DISINFECTING
Steps:
1. Wipe the A228/A248/A228I/A248I with a dry clean cloth.
2. Clean per Athena’s instructions in appendix B.
Cautions:
Do not immerse or the A228/A248/A228I/A248I and its peripherals. If you
accidentally spill liquid into the device, disconnect the unit from the power
source. Contact Athena regarding the continued safety of the unit before
placing it back in operation.
Do not use disinfectants that contain phenol.
Do not autoclave or clean the A228/A248/A228I/A248I or its peripherals
with strong aromatic, chlorinated, ketone, ether, or Esther solvents, sharp
tools or abrasives. Never immerse electrical connectors in water or other
liquids.
