Step 6

Calibrate

At the end of the 2-hour start-up period, you’ll calibrate your 

device by taking 2 fingerstick readings with your BG meter 

(within 5 minutes or less of each other) and then immediately 

entering them into your Receiver. You’ll also need to calibrate 

daily with 1 fingerstick approximately every 12 hours. 

Calibrations can be entered sooner if desired. 

To Calibrate:

a.  After 2 hours, the Double Blood-Drop screen will appear 

on your Receiver. Press 

C

.

 

 

 

 

 

b.  Wash hands, perform fingerstick, and get reading with BG 

meter.

c.  Press 

OK

 on Receiver.

d.  Scroll to highlight 

Enter BG

. Press 

OK

.

e.  Scroll to enter BG reading. Press 

OK

.

f.  Press 

OK

 a second time to confirm.

g.  Repeat instructions (starting with step b) to enter second 

fingerstick reading. Both readings need to take place 

within 5 minutes or less of each other and be entered into 

the Receiver immediately. 

h.  Two calibrations are needed each day (more calibrations 

per day are OK, but not necessary). Every 12 hours you’ll 

be prompted to enter another fingerstick reading; follow 

above instructions (steps b-f). Remember, you can cali

-

brate sooner than every 12 hours if desired.

Step 3

Set High/Low Alerts

Based on the alert levels you set, your Receiver can alert 
you when your Sensor readings become too high or too low. 
These alerts are not meant to be your target levels, but the 
levels at which you want to be alerted so you can treat 

before

 

you get too high or too low. You can leave levels at default 
settings (high: 200 mg/dL; low: 80 mg/dL) or customize them 
based on personal experience or suggestion from your health 
care provider.

To Set High/Low Alerts:

a.  Press 

OK 

to enter Main Menu.

b.  Scroll to highlight 

Alerts

. Press 

OK

.

c.  

High Alert

 will be highlighted. Press 

OK

.

d.  Highlight desired alert type. Press 

OK

e.  Use 

qp

 buttons to set glucose level. Press 

OK

.

f.  Snooze feature is defaulted as “none” or “off.”  Press 

OK

.

Note: See “Beyond the Basics” on back or refer to your 

User’s Guide to learn about additional alert options, 

 

including “snooze.”

g.  Repeat above instructions to set

 Low Alert

.

Step 2

Set Time/Date and ID

Initially, you’ll need to set the time and date. Also, your 

Transmitter and Receiver need to be able to talk to each 

other—an ID code makes this possible. 

To Set Time/Date:

a.  Press any button to turn Receiver on.
b. Press

 OK 

to enter Main Menu.

c.  Scroll (using 

qp

 buttons) to highlight 

Settings

. Press 

OK

.

d.  Time/Date will be highlighted. Press

 OK

.

e.  Use 

qp

 buttons to set time/date. Press 

OK

.

To Set ID (Note: ID may already be set):

a.  Press 

OK

 to enter Main Menu.

b.  Scroll to highlight 

Settings

. Press 

OK

.

c.  Scroll to highlight

 Transmitter ID

. Press 

OK

.

d.  Use 

qp

 buttons to set 5-digit ID number (found on flat 

side of Transmitter). Press 

OK

.

 

Step 4

Insert the Sensor

Sensor insertion is quick and easy. Before starting this step, 

you should have a Sensor Applicator, the Transmitter, and 

alcohol wipes at hand.

To Insert the Sensor:

a.  Clean the placement site with alcohol. Let dry. (Placement 

site: on your belly, out of the way of waistband or areas 

where you put pressure while sleeping and at least 3 

inches away from insulin pump infusion set if applicable).

b.  Remove adhesive tabs from bottom of 

 

Sensor Pod. 

 

 

c.  Place Sensor horizontally, NOT vertically. 

 

Rotate your fingers around adhesive 

 

to secure.

 

d.  Remove Safety Lock/

Transmitter Key by 

 

pulling straight out  

(follow arrows in picture). 

Save Transmitter Key.

 

e.  Using your thumb and finger, it may help to pinch up on 

your skin at base of the Sensor Pod (use non-dominant 

hand). 

f.  With dominant hand, 

place 2 fingers 

above

 

collar (see picture). Put 

your thumb on plunger and push down completely. 

 

You should hear 2 clicks.

g.  Using your thumb as a base, place your 

 

2 fingers 

below

 the collar and pull up  

completely.

h.  Make sure the Transmitter Latch is flush 

against the skin. While still holding the 

Sensor Applicator, use your other hand 

to squeeze ribbed tabs on sides of 

 

Sensor Pod. Rock the Sensor Applicator 

 

forward and lift up and away from your body.

To Attach the Transmitter:

a.  Clean Transmitter with alcohol wipe. Let dry.
b.  Using your thumb and finger, it may help to pinch up on 

your skin at the base of the Sensor Pod. Place Transmitter 

in Sensor Pod (flat side down, thinner side away from latch). 

c.  Use a finger to hold Transmitter in 

place. With your other hand, move 

Transmitter Latch forward until you 

hear 2 clicks.

d.  To remove Transmitter Latch, hold 

sides of Sensor Pod with one hand and 

Transmitter Latch with the other. Twist 

off Latch.

Step 1

Get to Know Your 

Your SEVEN PLUS is made up of 3 components: the Re

-

ceiver, the Transmitter, and the Sensor Applicator/Sensor. 

Note: Your Receiver must be fully charged before you 

begin these steps. A full charge can take up to 3 hours; 

the Battery indicator will continue to fill until you take 

your Receiver off the charger.

previous screen)

Transmitter

 (NOT DISPOSABLE!)

Note: Keep your Transmitter within 

 

5 feet of your Receiver for best 

 

communication, even during the 

 

start-up period.

Step 5

Start the Sensor Session

Once you’ve inserted the Sensor, your Receiver needs to 

know it’s there. 

To Start the Sensor Session:

a.  Make sure antenna symbol 

 is visible (lower right 

corner of Receiver). Press 

OK

.

b.  Scroll down to highlight 

Start Sensor

. Press 

OK

.

 

c.  Starting screen will appear and Receiver will return to 

trend graph. The 2-hour start-up period has begun (no 

data displayed during start-up); grayed-out Status Box 

will gradually disappear. 

Step 7

End the Sensor Session

The Sensor automatically shuts off after 7 days (the Re

-

ceiver will alert you before this happens), or you can shut it 

off at any time by choosing the 

Stop Sensor

 menu option. 

To Remove the Sensor Pod and Transmitter:

a.  Loosen adhesive and peel Sensor Pod/Transmitter from 

body. 

b.  Place Sensor Pod/Transmitter on hard surface. 

Insert jagged edges of Transmitter Key (from Sensor 

Applicator) so they “hug” Transmitter wings in Sensor 

Pod. 

c.  Press Transmitter Key down until you cannot press 

anymore and then pull up. The Transmitter will pop out of 

the Sensor Pod.

 

 

 

 

 

 

 

Note:  If you did not keep the Transmitter Key, you can 

use your fingers and spread out the back tabs of the 

Sensor Pod. The Transmitter will then pop out.

d.  Keep Transmitter.
