Fit the cover into the case and screw down the knob while
firmly pushing in to close� Ensure the cover is firmly screwed
into place�
NOTE: When replacing batteries, use 6 C cells that are the
same type� Do not mix Alkaline with NiCd (NiCad or Nickel
Cadmium) for example� Be sure to replace with batteries
where all of the cells have the same amount of charge� Do
not mix half used alkalines with brand new ones�
Operation Time
Typical operation time varies for the ST-305, depending on
factors such as load, environment, and current transmitted�
Operation at low temperatures will also reduce battery life�
Batteries often recover after being subjected to high loads� If
time is allowed, batteries may recover enough to offer addi-
tional hours of operation�
Battery Check
At start-up, the ST-305 will check available power and will
indicate estimated battery levels by lighting one, two, or
three LEDs in the right hand column (power level) on the
control panel� One LED indicates low batteries, two indicate
medium charge, and three LEDs indicate full battery charge
is available� These levels are only estimates based on a
rapid internal check� A rapid series of beeps will sound if the
battery levels run low in operation�

Sounds of the ST-305

Sounds are associated with specific events or states; they
include:
• Beeps – Beeps when current is flowing; rate increases
with current increase�
• Beeps – Turn ON (4 beeps)/OFF (3 beeps)�
• Short Double Tone – Inductive Clamp connected�
• Long-Short-Short Tone – Inductive Mode�
• Rapid series of beeps – Low Battery Warning�
The sound may be toggled on or off by pressing the Frequen-
cy and Power buttons simultaneously�

Powering ON / OFF

Turn the unit ON by pressing the Power Key� The current
frequency and power-level LEDs will light up�
Turn the unit OFF by pressing and holding the Power Key
for 2 seconds� Three tones will sound�
Automatic Shut Down
To save energy, the ST-305 will automatically shutdown after
an interval which varies with the power setting:
