CAUTION:
• Only use a penlight battery (1.5 V) when
checking the LEDs. Other batteries (e.g.,
alkaline batteries or high-voltage batter-
ies) will damage the diodes.
• Do not apply more than 1.7 V to the
leads when checking the LEDs.
NOTE:
A feature of LEDs is that they only allow cur-
rent to flow in one direction.
