section 4: determining proper meal size
The NANO Automated Pet Feeder uses a dual-beam weigh mechanism and digital microprocessor to provide PRECISION PORTION CONTROL by dispensing food
based on weight. Other automated feeders dispense food based on volume, which can potentially under or overfeed the pet due to the variation and inconsistency
between kibble sizes.
Because many users may be more familiar with determining a portion based on Cups, see below for an Estimated Conversion Guide.
This guide was created using the average measurements of 10 of the top selling cat and dog foods.
If a more precise conversion is necessary, use the following steps to calculate the exact conversion from Ounces or Grams to Cups
for your preferred pet food.
Use MANUAL FEED to Calculate Meal Size:
1) Press the MANUAL FEED button until an appropriate meal size is dispensed. Make reference to the amount in Ounces or Grams dispensed on the LCD Display.
Note: Ounces or Grams dispensed will appear on the display for 10 seconds.
2) Validate the amount dispensed against a measuring cup. If this dispensed too much or too little, repeat this process as needed until the proper
MEAL SIZE is confirmed.
3) Note the conversion from Cups to Ounces or Grams of your preferred food. This will be your desired MEAL SIZE for this specific pet food. If you change pet foods,
it will be necessary to reverify.

The CLOCK function programs the real-time clock on the unit. Once the CLOCK
has been set, the unit will retain the time if the unit is plugged in or powered
by battery backup. The unit will retain CLOCK time even if it is turned o.
Power Failure: In the event of a complete loss of power (Wall Outlet &
Backup Battery), the unit will lose all user defined program settings. This
will be indicated by the CLOCK time flashing. Resetting CLOCK, MEAL TIME and
MEAL SIZE programming will be necessary.

preset meals
The PRESET MEALS function is the quickest way of selecting a customized
daily meal schedule. The NANO has (6) Preset Meal options to choose from.
Once selected, it will override the DEFAULT MEAL SETTINGS.
Note: If a Preset Meal option is selected, it will become your meal schedule.
It can then be further customized as desired in MEAL TIME AND MEAL SIZE
programming. (page 3)
IMPORTANT: Pressing “PRESET MEALS” button in the middle of adjusting
setting will exit PRESET MEALS programming, WITHOUT saving any changes.
If no keys are pressed in 30 seconds, PRESET MEALS programming will end
WITHOUT saving any changes.
The MEAL TIME function allows the user to program the exact time of day
meals are dispensed. The NANO can program up to (6) Meal Times per day.
If a Preset Meal option was previously selected, it will start as your MEAL
TIME programming. It can be further customized as desired. Each day of the
week will be programmed with the same MEAL TIME schedule.
It is NOT possible to program dierent Meal Times based on the day of the
week. For example, to alter Meal Times on the weekends.
Note: If a MEAL TIME is accidentally created, it can be erased by selecting
the flashing MEAL TIME #, and holding ENTER for 2 seconds. Once a meal is
erased - DASHES will replace the MEAL TIME.
The MEAL SIZE function allows the user to adjust how much food is dispensed
at programmed meal times.
Note: Each MEAL TIME will dispense the same MEAL SIZE.
Tip: MEAL SIZE is dispensed in either Ounces or Grams. To convert to Cups refer
to CALCULATING MEAL SIZE FROM OUNCES OR GRAMS TO CUPS. (page 5)

pets that have issues with eating too fast.
Note: The full MEAL SIZE programmed will still be dispensed, only at
a slower speed.

Tip: If cups is a more familiar food portion, refer to CALCULATING MEAL SIZE
FROM OUNCES OR GRAMS TO CUPS. (page 5)
The POWER BUTTON allows the user to turn o the unit while maintaining
the user defined CLOCK, MEAL TIME and MEAL SIZE Programming. This is
helpful when you want to temporarily suspend dispensing meals, like an out
of town trip.

low battery
The LOW BATTERY LED will illuminate if the Backup Batteries are low and
need to be replaced.
NOTE: The Battery Low LED will flash slowly if the unit has become
unplugged.
The unit is NOT intended to run on batteries alone. Batteries are a backup
to ensure user defined CLOCK, MEAL TIME and MEAL SIZE programming are
maintained in the event of a power outage.
Tip: Backup Batteries should be changed when the Power Supply is
plugged in to ensure user defined CLOCK, MEAL TIME and MEAL SIZE
programmed is not lost.
error
The NANO will attempt to dislodge and self correct a Food Jam. In the
event this cannot be done, the ERROR LED will illuminate. Refer to
TROUBLESHOOTING for instruction on how to fix a food jam.
If the error LED stays on after troubleshooting, contact Customer Support:
1-877-PETMATE (1-877-738-6283)

section 6: troubleshooting
1) If no time is shown on the LCD Display:
a) Turn on Power Button. It is possible the unit is in the O Mode.
b) Make sure wall outlet is functioning by plugging in a dierent
electrical device.
c) Check connection of Micro USB Plug and Universal USB Power Supply. It
is possible the connection has come loose.
d) Change Backup Batteries.
2) If the clock is flashing:
a) The unit has lost power. Resetting user defined CLOCK, MEAL TIME and
MEAL SIZE programming will be necessary.
b) Note: Until unit is reprogrammed, it will revert to the
DEFAULT MEAL SETTINGS.
3) If “Error” indicator is flashing, this indicates the unit did
not completely deliver the full amount of food programmed
for the meal:
a) Turn unit o by using Power Button, empty the Food Hopper.
b) Check for food jamming in the throat of the Base Unit. Note: To avoid
damaging the unit, DO NOT use tools.
c) Check for jamming around food discharge door.
d) Dislodge any food jams. Reminder: Works best with ½” food diameter
food or smaller.
e) Re-assemble, refill with food and turn on unit.
f) Press the MANUAL button on the display to ensure the unit will properly
dispense food. Note: If clock is flashing, unit has lost all power.
Resetting user defined CLOCK, MEAL TIME and MEAL SIZE programming
will be necessary.
4) Error light is flashing, with an overfilled bowl:
a) Unit is not able to dispense based on food being unable to fall from the
Base Unit.
b) Empty the bowl so future meals can dispense properly.
c) If overfilling is consistently happening, the user defined MEAL SIZE
should be reduced.
5) If the “LOW BATTERY” indicator light is lit:
a) Ensure Micro USB Plug is connected to Base Unit and Universal USB
Power Supply is plugged into wall outlet. Make sure no connections
have come loose.
b) Make sure wall outlet is functioning by plugging in a dierent electrical
device.
c) Refer to the Battery installation instructions and install new batteries.
d) If clock is flashing, unit has lost all power. Resetting user defined CLOCK,
MEAL TIME and MEAL SIZE programming will be necessary.
